FUNDAMENTALS
[001] When wells are prepared for oil and gas production, it is common to cement a lining column inside the hole. Often, it may be desirable to cement the casing column into the well in separate, multiple stages. The casing column can be run inside the well to a predetermined depth. Several "zones" in the underground formation can be isolated through the operation of one or more obturators, which can also help to secure the coating column and the stimulation equipment, and / or by cement.
[002] After placing the lining column, it may be desirable to provide at least one fluid communication path out of the lining column. Conventionally, the methods and / or tools employed to provide fluid paths outside the casing column require mechanical tools provided by equipment and / or downhole tools, requiring high temperature protection, batteries that last longer, and / or wired surface connections. In addition, conventional methods may not allow individual, or at least selective, activation of a fluid communication path of the plurality of training zones. SUMMARY
[003] In one embodiment, a wireless drive system consists of a transmitter, a drive system consisting of a receiving antenna, and one or more transient sliding components from a first position to a second position. The transmitter is configured to transmit an electromagnetic signal, and the sliding component prevents a fluid communication path through one or more compartment doors when the sliding component is in the first position. The sliding component allows fluid communication through one or more compartment doors when the sliding component is in the second position, and the drive system is configured to allow the sliding component to transition from the first position to the second position in response to the recognition of the electromagnetic signal by the receiving antenna.
[004] In one embodiment, a wireless drive system consists of a receiving antenna, a drive mechanism coupled to the receiving antenna, a pressure chamber, and a sliding component disposed in a downhole tool. The receiving antenna is configured to generate an electric current in response to the receipt of a signal, and the drive mechanism is configured to selectively activate fluid communication between the pressure chamber and the sliding component using the electric current. The sliding component is configured to transition from a first position to a second position based on a pressure differential between the pressure chamber and a second pressure source.
[005] In one embodiment, a drive system for a downhole component consists of a powered transmitter, consisting of a transmitting antenna and a downhole component consisting of a central flow control and an antenna receiver coupled to a drive system. The powered transmitter is configured to be received within the central flow control, and the transmitting antenna is configured to transmit a signal. The receiving antenna is configured to generate an electrical current in response to receiving the signal from the transmitting antenna, and the drive system is configured to operate using the electrical current from the receiving antenna.
[006] In one embodiment, a method for driving a downhole component comprises passing a powered transmitter through a central flow control of a downhole component; transmitting a signal from a transmitting antenna arranged on the powered transmitter; generating an electric current in a receiving antenna arranged in the bottom of the well in response to receiving the signal from the transmitting antenna; and activating a drive system using electric current. The downhole component may include a compartment comprising the drive system; and a sliding component positioned inside the compartment. The sliding component can be configured to transition from a first position to a second position. When the sliding component is in the first position, the sliding component can prevent a fluid communication path through one or more compartment doors, and when the sliding component is in the second position, the sliding component can allow fluid communication through one or more doors compartment doors.
[007] In one embodiment, a well screen assembly for use at the bottom of the well comprises a fluid path configured to provide fluid communication between an exterior of a tubular well equipment and an interior of the tubular well equipment; a flow restrictor disposed in the fluid path; a drive system, consisting of a receiving antenna and a sliding component arranged in series with the flow restrictor in the fluid path. The receiving antenna is configured to generate an electric current in response to the receipt of a first electromagnetic signal having a first frequency, and the sliding component is transient from a first position to a second position in response to the electric current. The sliding component prevents fluid communication along the fluid path when the sliding component is in the first position, and the sliding component allows fluid communication along the fluid path when the sliding component is in the second position.
[008] In one embodiment, a well screen assembly for use in a well is composed of a plurality of fluid paths. Each fluid path of the plurality of fluid paths is configured to provide fluid communication between an exterior of a tubular well equipment and an interior of the tubular well equipment, and two or more fluid paths of the plurality of fluid paths make up a drive system composed of a receiving antenna and a sliding component arranged in the corresponding fluid path. The receiving antenna is configured to generate an electric current in response to the receipt of a specific first electromagnetic signal, and the sliding component is transient from a first position to a second position in response to the electric current. The sliding component prevents fluid communication along the corresponding fluid path when the sliding component is in the first position, and the sliding component allows fluid communication along the corresponding fluid path when the sliding component is in the second position. The drive systems in each of the two or more fluid paths can be configured to generate the electric current in response to specific electromagnetic signals, having different frequencies.
[009] In one embodiment, a method comprises the prevention, by a sliding component, of the fluid flowing through a fluid path in a well screen assembly, coupling by induction, by a receiving antenna, with a transmitting antenna that is transmitting a first signal, generating an electrical current in the receiving antenna in response to receiving the first signal, transferring the sliding component using the electrical current, and allowing the flow to flow through the fluid path in response to the transfer of the sliding component. The fluid path is configured to provide fluid communication between an exterior of a tubular well equipment and an interior of a tubular well equipment. A flow restrictor can be arranged in the fluid path. BRIEF DESCRIPTION OF THE FIGURES

[0020] In the drawings and description below, similar parts are typically marked throughout the specification and drawings with the same reference numbers, respectively. In addition, similar reference numerals can refer to similar components in different modalities disclosed in this document. The figures in the drawings are not necessarily to scale. Certain features of the invention may be shown exaggeratedly in scale or in a somewhat schematic form and some details of conventional elements may not be shown for the sake of clarity and conciseness. The present invention is susceptible to modalities in different ways. The specific modalities are described in detail and are shown in the drawings, with the understanding that the present disclosure is not intended to limit the invention to the modalities illustrated and described in this document. It must be fully recognized that the different teachings of the modalities discussed here can be used separately or in any suitable combination to produce the desired results.
[0021] Unless otherwise specified, the use of the terms "connect", "engage", "engage", "attach", or any other term that describes an interaction between elements is not used to limit the interaction for interaction between the elements and may also include indirect interaction between the elements described. Unless otherwise specified, use of the terms "above", "top", "up", "top of the well", or other terms, should be interpreted as generally forming towards the surface or towards the surface of a water structure; likewise, use of "down", "bottom," "down", "rock bottom", or other terms, should be interpreted as generally within the formation away from the surface or away from the surface of a water structure , regardless of the direction of the well. Use of one or more of the aforementioned terms cannot be interpreted as denoting positions along a perfectly vertical axis. Unless otherwise specified, use of the term "underground formation" should be understood to encompass both areas below ground and areas below ground covered by water, such as the sea or fresh water.
[0022] The configuration of a well can be varied over the life of the well. This can allow the desired zones to be opened or closed to the flow, or the flow characteristics adjusted during production. To implement this adjustment, a tool can be inserted into the well to physically change the configuration of the drilling, completion and / or production column components. For example, a valve can be operated manually with a locking mechanism, attached to a steel cable (slickline), coiled tubing, or the like, which requires a physical presence inside the well. These operations can be expensive and arduous. As disclosed here, a tool such as the Wireless Activatable Valve Assembly (WAVA) can be used to adjust the configuration of the flow paths within the well. WAVA can effect a change in the variation of a well assembly using an electric actuator coupling to a transmitter disposed inside the well. For example, WAVA may rely on one or more batteries to supply power to drive systems, receivers, actuators, and / or any other components. Such modes can be used for a limited time, corresponding to the life of the batteries.
[0023] In some modalities, a power source such as a battery may not be present. Instead, the electric actuator can have its energy supplied based on the inductive coupling to a receiving antenna with a transmitter arranged in the well. When a receiver coupled to the trigger receives the correct frequency (for example, a resonant frequency), an electrical current can be generated in the receiver that is sufficient to trigger the electric trigger. In this modality, the electric actuator can be without power inside the well-bottom assembly until necessary. When it is desired to activate the electric actuator, a transmitter can be arranged in the well that is configured to transmit the correct frequency to induce a current in the receiver. Once the receiver can be adjusted to be frequency sensitive, a transmitter may be able to trigger only the desired electrical trigger, leaving another electrical trigger that is set to other frequencies unaffected. Thus, the wireless drive tools disclosed in this document may allow selective activation of one or more flow paths that can be arranged in a plurality of zones in the well without the need for physical intervention in the well, except the provision of a transmitter inside the well. As such, the disclosed wireless drive tools can provide an operator with greater control and flexibility to program the activation of multiple valves, offering a potential activation period that extends beyond the life of any batteries used with a well tool.
[0024] Disclosed in this document are modalities of a WAVA, as well as systems that can be used in carrying out the same. Particularly, disclosed in this document are one or more modalities of a WAVA configured for selective activation and methods of using it in the maintenance and / or completion of a well. In one embodiment, MAVA and / or the methods of using it, as disclosed here, may allow an operator to open and / or close one or more valves by a wireless mechanism, such as producing one or more zones in a underground formation and to produce a formation fluid from there.
[0025] Referring to Figure 1, in a modality of an operational environment in which the WAVA and / or method can be used is illustrated. It is noted that although some of the figures may exemplify horizontal or vertical wells, the principles of the methods, devices and systems disclosed in this document may be equally applicable to conventional horizontal and vertical well configurations or combinations thereof. Therefore, unless otherwise indicated, the horizontal, vertical or deviation nature of any figure should not be construed as limiting the well in any special configuration.
[0026] Referring to the embodiment of Figure 1, the operating environment generally comprises a well 114 that penetrates an underground formation 102. Furthermore, in an embodiment, the underground formation 102 may comprise a plurality of formation zones 2, 4, 6, 8, 10, 12, 14, 16 and 18, for the purpose of hydrocarbon recovery, hydrocarbon storage, carbon dioxide elimination, or the like. Well 114 can be drilled in underground formation 102 using any suitable drilling technique. In one embodiment, a drilling or maintenance platform 106 comprises a derrick 108 with a drilling deck 110 through which one or more tubular columns (for example, a working column, a drilling column, a tool column , a column of segmented tube, a column of articulated tubes, or any other suitable means of transport or combinations thereof) generally defines an axial flow path that can be positioned inside or partially inside well 114. In one embodiment, a tubular sequence it may comprise two or more concentric positioned tube or pipe column chains (for example, a first working column can be positioned within a second working column). The drilling or maintenance platform 106 may be conventional and may comprise a winch driven by motor and other associated equipment to transport the work column into well 114. Alternatively, a mobile reconditioning platform, a well maintenance unit (for example , coiled tubing units) or the like, can be used to transport the tubular column into well 114. In such an embodiment, the tubular column can be used in drilling, stimulating, completing or otherwise maintaining the well, or combinations thereof .
[0027] Well 114 may extend substantially vertically away from the earth's surface over a vertical part of the well, or it may deviate at any angle from the earth's surface 104 over a deviated or horizontal part of the well. In alternative operating environments, parts or substantially the entire well 114 may be vertical, offset, horizontal and / or curved. In one embodiment, well 114 may be a new well or an existing well and may comprise an open well, coated well, cement-coated well, pre-drilled liner well, or any other appropriate configuration or combinations thereof. For example, in the embodiment of Figure 1, a coating column 115 is positioned within at least part of the well 114 and is secured in position with respect to the well with cement 117 (for example, a cement sheath). In alternative modalities, parts and / or substantially all wells can be coated and cemented, coated and non-cemented, uncoated, or combinations thereof. In another alternative embodiment, a coating column can be fixed against formation using one or more suitable plugs, such as mechanical plugs or expandable plugs (for example. Uwg'llPcekg'ru ™. EqogtekclogpVg fkurqpixgn rqt Jcnnkdwrtqp Gpgti {Services).

[0030] As used in this document, the term "EM signal" refers to an electromagnetic signal. For example, an electrical signal can be transformed into an electromagnetic (EM) signal by inciting a nearby electric field and / or a nearby magnetic field, thereby generating an electromagnetic signal. In addition, the EM signal can be transmissible through a transmitting antenna (for example, an electrically conductive material, for example, a copper wire). Not wishing to be limited to theory, the EM signal is usually composed of an oscillating electric field and an oscillating magnetic field, propagating at a speed proportional to or almost the speed of light. In addition, the EM signal can be transmitted in an adequate magnitude of the transmission power, as would be appreciated by those skilled in the art who have the benefit of this disclosure. In addition, the EM signal can generally include polarized waves, non-polarized waves, longitudinal waves, transverse waves, and / or combinations thereof. The EM signal can be receivable and can be transformed into an electrical signal (for example, an electrical current), through a receiving antenna (for example, an electrical conductive material, for example, a copper wire), as disclosed in this document .
[0031] In one embodiment, the EM signal can be characterized as comprising any suitable type or configuration of waveform or combination of waveforms, having any suitable characteristics or combinations of characteristics. For example, the EM signal can include one or more sinusoidal signals and / or one or more modulated analog signals, for example, through amplitude modulation, frequency modulation, phase modulation, quadrature amplitude modulation, space modulation, single sideband modulation, similar, or combinations thereof. In one embodiment, the EM signal can have any appropriate duty cycle, frequency, amplitude, phase, duration or combinations of these, as would be appreciated by those skilled in the art and with the benefit of this disclosure. For example, in one embodiment, the EM signal may include a sine waveform with a frequency within a frequency range of about 3 kHz to about 300 GHz, alternatively, about 100 kHz to about 10 GHz, alternatively, about from 120 kHz to about 3GHz, alternatively, about 120 kHz to about 920 MHz, alternatively, at any appropriate frequency as would be appreciated by those skilled in the art and with the benefit of this disclosure. Additionally or alternatively, in one embodiment, the EM signal can include one or more modulated digital signals, for example, through amplitude switching modulation, continuous phase switching modulation, frequency switching modulation, multiple frequency switching modulation , minimum switching modulation, on-off switching, phase switching modulation, the like, or combinations thereof. For example, the EM signal can have any appropriate data rate, transmission rate, and / or amplitude, as would be appreciated by those skilled in the art and with the benefit of this disclosure. For example, in one embodiment, the EM signal may comprise a digital on-off switching modulation at any appropriate data rate.

[0037] In one embodiment, the MAVA 200 can be configured by incorporating it into the tubular column of well 120 and / or another suitable tubular column. In one embodiment, compartment 210 may include an appropriate connection for the tubular column of hole 120 (for example, for a component of the coating column, such as a coating joint), or, alternatively, on any suitable column (for example , a liner, a working column, a coiled pipe column or another tubular column) For example, housing 210 may include threaded surfaces internally or externally. Additional or alternative suitable connections for a coating column (for example, a tubular string) will be known to those skilled in the art when viewing this disclosure.
[0038] In the embodiment of Figures 3A-3B and 6A-6C, compartment 210 generally defines flow passage 36, for example, a flow passage 36 can generally be defined by the internal surface of well 238 of compartment 210. In such a way In this embodiment, the WAVA 200 is incorporated within the tubular column of the well 120 so that the flow passage 36 of the WAVA 200 is in fluid communication with the flow passage 121 of the tubular column of the well 120.

In one embodiment, the first axial surface 234 can be positioned on an interface at the top of the well of the cylindrical surface of the well 230. Also in such an embodiment, the second axial surface 234 can be positioned on a downhole interface. from the cylindrical surface of well 230. While illustrated as cylindrical wells, sliding chambers comprising any suitable cross section can be used with sliding components having corresponding cross sections. In additional or alternative styles, compartment 210 may additionally comprise one or more indentations, cutouts, chambers, voids or the like, where one or more components of the drive system 226 may be arranged, as disclosed in this document.
[0040] In one embodiment, compartment 210 comprises one or more doors 212. In one embodiment, one or more doors 212 may be arranged circumferentially around an inner and / or outer surface of compartment 210. For example, doors 212 can comprise an outer port orifice 212a and an inner port orifice 212b and can extend radially out of and / or inward toward flow passage 36, as shown in Figure 4. As such, these ports 212 can provide a fluid communication path between flow passage 36 and an exterior of compartment 210 when the WAVA 200 is configured for. For example, the WAVA 200 can be configured so that ports 212 provide a fluid communication path between the flow passage 36 and the exterior of the WAVA 200 (for example, the annular space extending between the WAVA 200 and the walls from well 114 when the WAVA 200 is positioned inside the well) when the fluid communication path of ports 212 is unblocked (for example, by the sliding component 216, as disclosed in this document). Alternatively, the MAVA 200 can be configured so that no fluid is transmitted through ports 212 between flow passage 36 and the exterior of the MAVA 200 when the fluid communication path of the ports is blocked (for example, by the sliding component 216, as disclosed in this document). When a plurality of WAVA is arranged in the sliding chambers arranged circumferentially around the flow passage of the housing 210, each WAVA can be configured to operate in response to it or at a different frequency like any other WAVA, as described in more detail here. This can allow for selective opening or reconfiguration of the individual sliding chambers.

[0042] In an alternative embodiment, as illustrated in figures 6A-6C, compartment 210 may comprise an outer door 212c, an inner door 212d and a bypass door 410. In one embodiment, outer door 212c may provide a pathway fluid communication between the exterior of compartment 210 and one or more chambers within compartment 210 (for example, an inlet chamber 412), as disclosed herein. In addition, the inner door 212d can be arranged along the cylindrical surface 230 of the sliding chamber 220 and the inner door 212b can provide a fluid communication path between the sliding chamber 220 and the flow passage 36 of the compartment 210. In addition, in one embodiment, the bypass port 410 can be arranged within the inlet chamber 412 of compartment 210 and can provide a fluid communication path between the inlet chamber 412 and flow passage 36 of compartment 210.
[0043] In an additional embodiment, one or more of ports 212 (for example, outer door 212c) can be positioned adjacent to a plug, a screen, a filter, a "coiled wire" filter, a sintered mesh filter , a pre-packaged filter, an expandable filter, a slit filter, a perforated filter, a cover, or a shield, for example, to prevent debris from entering doors 212. For example, in a mode as illustrated in the Figures 6A-6C, the WAVA 200 may further include a filter 402 (for example, a "coiled wire" filter) positioned adjacent to and / or covering outer port 212c, and filter 402 may be configured to allow fluid to pass , excluding sand or other debris larger than a certain size. In an additional or alternative embodiment, ports 212 may comprise one or more pressure-changing devices (for example, nozzles, erodible nozzles, jets of fluid or the like).
[0044] In an additional or alternative embodiment, compartment 210 may comprise entrance chamber 412. In the embodiments of Figures 6A - 6C, entrance chamber 412 may provide a fluid communication path between the exterior of compartment 210 and the passage flow rate 36 of compartment 210, for example, through external port c 212c and a flow restrictor 404 and / or bypass port 410, when configured to do so, as disclosed in this document.
[0045] In one embodiment, the flow restrictor 404 can be arranged within compartment 210 to provide a fluid communication path between the inlet chamber 412 and the sliding chamber 220. In such an embodiment, the flow restrictor 404 can be configured to cause a fluid pressure differential through flow restrictor 404 in response to communication of a fluid through flow limiter 404 in at least one direction. In one embodiment, the flow limiter 404 may be cylindrical in shape and may comprise at least one fluid passage, extending axially through the flow restrictor 404 having a diameter significantly less than the length of the passage. In an additional or alternative embodiment, the flow restrictor 404 may be formed from a restrictor orifice, a restrictor nozzle, a helical restrictor, a u-curvature restrictor, and / or any other types of metering suitable to create a differential pressure through flow restrictor 404. In some additional or alternative embodiments, the flow restrictor 404 may allow unidirectional fluid communication, for example, allowing fluid communication in a first direction with minimal resistance and substantially preventing fluid communication in a second direction (eg providing high strength). For example, in one embodiment, the flow restrictor 404 may comprise a check valve or the like to provide one-way fluid communication.
[0046] In one embodiment, the fluid communication path provided by flow restrictor 404 may be at least partially more restrictive (e.g., more resistance) than the fluid communication path provided through bypass port 410. For example , in one embodiment, a flow may flow at a lesser flow rate and / or with a greater pressure drop through flow restrictor 404 than through bypass port 410.
[0047] In an embodiment as shown in Figures 6A - 6C, a bypass valve 416 can be arranged inside the inlet chamber 412 and can be configured to selectively allow or disallow fluid communication between the inlet chamber 412 and the passage of flow 36 from compartment 210 through bypass port 410, as disclosed in this document. In one embodiment, the bypass valve 416 may comprise an actuating valve, a sliding component, a rupture disc or any other suitable device to selectively allow or prohibit a fluid communication path, as would be appreciated by those skilled in the art and who have the benefit of this disclosure. For example, in one embodiment, by activating (eg, opening) the bypass valve 416 the WAVA 200 can be configured so that a fluid can be allowed to communicate between the inlet chamber 412 and the flow passage 36 of the compartment 210 through the bypass port 410. In one embodiment, the bypass valve 416 comprises a sliding component 416, a driver 415 and a receiver 417. The driver 415 and / or receiver 417 can be configured to operate in response to a different frequency and / or EM signal than the receiver 218. This can allow trigger 250 to be triggered without activating trigger 415 and vice versa.
[0048] In figures 3A-3B and figures 6A - 6C, the sliding component 216 can be configured to selectively allow or disallow a fluid communication path between the exterior of compartment 210 and the flow passage 36 of compartment 210. In the embodiment of Figure 5, the sliding component 216 generally comprises a cylindrical or tubular structure and can be dimensioned to be slidably and concentrically mounted in a corresponding well, as disclosed in this document. In one embodiment, the sliding member 216 may include a unitary structure; alternatively, the sliding component 216 can be composed of two or more operably connected segments (for example, a first segment, a second segment, etc.). Alternatively, the sliding member 216 can comprise any suitable structure. Such suitable structures will be appreciated by those skilled in the art who have the benefit of this disclosure. In one embodiment, the sliding component 216 may comprise a cylindrical surface of the sliding component 216a, a first surface of the sliding component 216c, and a second surface of the sliding component 216d.
[0049] As shown in Figure 5, the sliding component 216 can be slidably positioned inside the compartment 210 (for example, inside the sliding chamber 220). For example, in the embodiment of Figure 5, at least a portion of the cylindrical surface of the sliding component 216a can be slidably mounted against at least a portion of the cylindrical surface of well 230 of compartment 210 in a fluid-tight or substantially fluid-tight manner. In one embodiment, the sliding component 216 may additionally comprise one or more suitable seals (for example, O-ring rings, T-seals, gasket, etc.) on one or more surface interfaces, for example, for purposes of restraint or prohibition of fluid movement through such a surface interface. In the embodiment of Figure 5, the sliding component 216 comprises seals 215 at the interface between the cylindrical surface of the sliding component 216a and the cylindrical surface of the well 230.
[0050] In one embodiment, the sliding member 216 and one or more seals 215 can be arranged within the sliding chamber 220 of compartment 210 so that at least one upper part of the sliding chamber 220 (e.g., a first chamber part 220a) can be fluidly connected to a lower part of the sliding chamber 220 (for example, a second part of the chamber 220b and a third part of the chamber 220c) In such an embodiment, the first chamber part 220a can generally be defined by the first axial surface 234, the first surface of the sliding component 216c, and at least a part of the cylindrical surface of the well 230 extending between the first axial surface 234 and the first surface of the sliding component 216c. Additionally, in one embodiment, the second chamber part 220b and the third chamber part 220c can be isolated from each other, for example, by means of a driving component 222 (for example, a rupture plate, a driving valve), as disclosed in this document. In such an embodiment, the second chamber part 220b can generally be defined by the second surface of the sliding component 216d, the driving component 222, and at least a part of the cylindrical surface of the well 230 extending between the second surface of the sliding member 216d and the driving component 222. Also, in such an embodiment, the third chamber part 220c can generally be defined by the driving component 222, the second axial surface 236, and at least a part of the cylindrical surface of the well 230 extending between the driving component 222 and the second axial surface 236.
[0051] In one embodiment, the first chamber part 220a, the second chamber part 220b, and / or the third chamber part 220c can be characterized as having a variable volume. For example, the volume of the first chamber part 220a, the second chamber part 220b and / or the third chamber part 220c can vary with the movement of the sliding component 216, as disclosed in this document.
[0052] In an embodiment, the sliding component 216 can be movable, in relation to the compartment 210, from a first position to a second position. In one embodiment, fluid communication between the flow passage 36 of the WAVA 200 and the outside of the WAVA 200, for example, through the outer door orifice 212a and the inner port orifice 212b of the doors 212, may depend on the position of the sliding component. 216 in relation to compartment 210.
[0053] Referring to the modalities of figure 3A and figure 6A, the sliding component 216 is illustrated in the first position. For example, in an embodiment as shown in Figure 3A, the sliding component 216 blocks the internal port orifice 212b of compartment 210 and thereby prevents fluid communication between the flow passage 36 of the WAVA 200 and the exterior of the WAVA 200 through the doors 212. In an alternative embodiment, in the first position the sliding component 216 can be positioned so that at least a part of the sliding component 216 is between the outer door orifice 212a and the inner door orifice 212b and thus block a path of fluid communication path between ports 212.
[0054] Referring to the modalities of figure 3B and figure 6B, the sliding component 216 is illustrated in the second position. In the second position, as shown in Figure 3B, the sliding component 216 does not block the internal port orifice 212b of compartment 210 and thus allows fluid communication from the flow passage 36 of the WAVA 200 to the outside of the WAVA 200 through ports 212.
[0055] In one embodiment, the sliding component 216 can be realized (for example, maintained) in the first position by an appropriate retention mechanism, as disclosed in this document. For example, in the embodiment of figure 3A, the sliding component 216 can be realized (for example, selectively maintained) in the first position by a hydraulic fluid, which can be selectively maintained within the second chamber part 220b by the drive system 226 (by example, to form a fluid block). In such an embodiment, while the hydraulic fluid is kept within the second chamber part 220b, the sliding member 216 can be prevented from moving towards the second position. On the other hand, as long as the hydraulic fluid is not kept within the second chamber part 220b, the sliding member 216 may be allowed to move in the direction of the second position. In one embodiment, for example, in the embodiment illustrated by Figure 3B, where the fluid is not kept within the second chamber part 220b, the sliding component 216 can be configured to transition from the first position to the second position after application of a pressure (for example, hydraulic) on the first surface of the sliding component 216c, as disclosed in this document.
[0056] In an additional or alternative embodiment, the sliding component 216 can be held in the first position by one or more shear pins. For example, one or more shear pins can extend between compartment 210 and sliding member 216. In such an embodiment, the one or more shear pins can be inserted or positioned within an appropriate hole in compartment 210 and the hole in sliding member 216. As will be appreciated by those skilled in the art, the one or more shear pins can be sized to distort or break by applying a force of desired magnitude (for example, force resulting from the application of a hydraulic fluid pressure , as a pressure test) on the sliding component 216, as disclosed in this document. In an alternative embodiment, the sliding component 216 can be held in the first position by any suitable frangible component, such as a shear ring or the like.
[0057] In one embodiment, the sliding component 216 can be configured to selectively transition from a first position to a second position. In one embodiment, the sliding component 216 can be configured to transition from the first position to the second position after activation of the drive system 226. For example, when activating the drive system 226 a pressure change within the sliding chamber 220 it can result in a differential force applied to the sliding component 216 towards the second position.
[0058] In such an embodiment, the sliding component 216 may include a differential in the surface area of the surfaces that are fluidly exposed to the first chamber part 220a (e.g., the second sliding component surface 216d) and the surface area of the surfaces which are fluidly exposed to the second chamber part 220b and / or the third chamber part 220c (for example, the first sliding component surface 216 c). For example, in one embodiment, the exposed surface area of the surfaces of the sliding component 216 that a force will be applied (for example, a hydraulic force), towards the second position (for example, a downward force) may be greater than the exposed surface area of the surfaces of the sliding component 216 that a force (for example, a hydraulic force) will be applied, in the opposite direction to the second position (for example, an upward force). For example, in the embodiment of Figure 3A and not having the intention to be limited by theory, the second chamber part 220b is fluidly sealed (for example, by one or more seals 115 and the driving member 222) and, therefore, not exposed to the hydraulic fluid pressures applied to the first part of the chamber 220a, thus resulting in a given differential in the force applied to the sliding component 216 towards the second position (for example a downward force) and the force applied to the sliding component 216 in the opposite direction to second position (for example, an upward force). . In an additional or alternative embodiment, a WAVA such as WAVA 200 may additionally comprise one or more additional chambers (for example, similar to the first chamber part 220a, the second chamber part 220b, and / or the third chamber part 220c) providing such a differential in the force applied to the first sliding component towards the second position and the force applied to the sliding component in the opposite direction to the second position. Alternatively, in one embodiment the sliding component 216 can be configured to move towards the second position, through a tensioning member, such as a spring or compressed fluid or through a control line or the signal line (for example, a hydraulic control line / conduit) connected to the surface.
[0059] In one embodiment, the hydraulic fluid can comprise any suitable liquid. In one embodiment, the hydraulic fluid can be characterized as having a suitable rheology. In one embodiment, the second chamber part 220b is filled or substantially filled with hydraulic fluid which can be characterized as a compressible fluid, for example a fluid having relatively compressibility, alternatively, the hydraulic fluid can be characterized as substantially incompressible. In one embodiment, the hydraulic fluid can be characterized as having a suitable volume modulus of elasticity, for example, a relatively high volume modulus of elasticity. For example, in one embodiment, the hydraulic fluid can be characterized as having a volume modulus ranging from about 1.8 105 psi, lbf / in2 to about 2.8 105 psi, lbf / in2 to about 1.9 105 psi, lbf / in2 to about 2.6 105 psi, lbf / in2, alternatively, from about 2.0 105 psi, lbf / in2 to about 2.4105 psi, lbf / in2. In an additional embodiment, the hydraulic fluid can be characterized as having a relatively low thermal expansion coefficient. For example, in one embodiment, the hydraulic fluid can be characterized as having a coefficient of thermal expansion in the range of about 0.0004 cc / cc / ° c to about 0.0015 cc / cc / ° c, alternatively, about 0.0006 cc / cc / ° ca approximately 0.0013 cc / cc / ° c, alternatively, about 0.0007 cc / cc / ° ca approximately 0.0011 cc / cc / ° c. In another additional embodiment, the hydraulic fluid can be characterized as having a stable fluid viscosity through a relatively wide temperature scale (for example, a working scale), for example, through a 50 ° F temperature scale at about 400 ° F, alternatively, from about 60 ° F to about 350 ° F, alternatively, from about 70 ° F to about 300 ° F. In another embodiment, the hydraulic fluid can be characterized as having a kinematic viscosity in the range of about 50 centistokes to about 500 centistokes. Examples of a suitable hydraulic fluid include, but are not limited to: oils, such as synthetic fluids, hydrocarbons or combinations thereof. Specific examples of a suitable hydraulic fluid include silicone oil, paraffin oil, petroleum based oils, brake fluid (fluids based on glycol ether, mineral based oils, and / or silicone based fluids), transmission, synthetic fluids or combinations thereof.
[0060] In one embodiment, the drive system 226 can be configured to transition the sliding component 216 from a first position to a second position. In addition, in one embodiment, the drive system 226 can be configured to selectively allow a fluid communication path within the WAVA 200 when receiving a predetermined EM signal, as disclosed in more detail in this document. For example, in one embodiment the drive system 226 can allow a communication path between two or more cameras 220 of the WAVA 200 when receiving a predetermined EM signal, for example, a transmitter 300 transmitting an RF signal of a predetermined frequency within the passage flow rate 36 of the WAVA 200. In addition, in one embodiment, the drive system 226 can be configured to selectively respond to one or more predetermined characteristics of an EM signal (for example, frequency, modulation), as disclosed in this document.
[0061] In one embodiment, the drive system 226 generally comprises a receiver 218 and a driver 250, as shown in Figure 5. In one embodiment, the receiver 218 and / or the driver 250 can be fully or partially incorporated within the WAVA 200 by any appropriate means as would be appreciated by those skilled in the art. For example, in one embodiment, receiver 218 and / or actuator 250 may be housed, individually or separately, within an indentation within compartment 210 of the WAVA 200. In an alternative embodiment, as will be appreciated by those skilled in the art, at least a part of the receiver 218 and / or the actuator 250 may be otherwise positioned, for example, outside the WAVA 200 compartment 210. It is understood that the scope of this disclosure is not limited to any particular configuration, position, and / or number of receivers 218, and / or actuators 250. For example, although the embodiment of Figure 5 illustrates a drive system 226 consisting of several distributed components (for example, a single receiver 218 and a single driver 250, each comprising a separate, distinct component), in an alternative embodiment, a similar drive system may include similar components in a single, unitary component; alternatively, the functions performed by these components (for example, the receiver 218 and the driver 250) can be distributed in any configuration and / or suitable number of similar components, as will be appreciated by those skilled in the art with the benefit of this disclosure.
[0062] In one embodiment, the receiver 218 can include a receiving antenna and can generally be configured to receive a signal (for example, an EM signal). The receiver 218 can provide an activation signal (for example, an analog voltage or current), which can be generated upon receipt of the EM signal, upon a determination that the receiving antenna has experienced the predetermined EM signal. For example, in one embodiment, receiver 218 may provide an activation signal (e.g., an electric current) to the driver 250 in response to receiving a predetermined EM signal (e.g., an RF signal of a predetermined frequency).
[0063] In one embodiment, the receiver 218 may include one or more receiver antennas. In one embodiment, the receiving antenna can be positioned inside compartment 210 of the WAVA 200 so that the receiving antenna can perceive EM signals within the flow passage 36 of compartment 210. In order to allow the EM signal to be detected by the receiving antenna , a window of material configured to allow the transmission of an EM signal can be arranged in the adjacent compartment or close to the receiving antenna. In such an embodiment, the one or more receiving antennas can be configured to receive a signal (for example, the EM signal) and can convert the EM signal into an appropriate electrical signal (for example, an electrical current). In an alternative embodiment, the one or more receiving antennas can be configured to inductively pair with a transmitting antenna and in response can provide an appropriate electrical signal (for example, an electrical current). For example, in one embodiment, a suitable electrical signal may include a variable voltage signal or a current signal indicative of the predetermined EM signal. In one embodiment, the receiving antenna may be configurable and / or adjustable to resonate and / or selectively respond to an EM signal comprising one or more predetermined frequencies. The receiving antenna may comprise a receiving circuit, or be adjusted based on the design of the receiving antenna (for example, based on coil length, diameter, etc.). For example, in one embodiment, the receiver may comprise a coiled receiving antenna and in response to receiving an EM signal of a predetermined frequency the inductively coiled receiving antenna may generate an EM field that can be transferred to an electrical current or an electrical voltage (for example, through inductive coupling) above a threshold value. In one embodiment, EM signals ranging from predetermined frequencies by more than a certain amount (for example, by more than about 5%, more than about 10%, more than about 15%, or more than about 20%) may not produce an inductive coupling, and / or may not generate an electrical current or voltage above the threshold value required to activate the WAVA.
[0064] In one embodiment, the receiving antenna may generally include an electrically conductive material such as one or more materials formed by aluminum, copper, gold, or any other suitable conductive material, as would be appreciated by those skilled in the art and with the benefit this disclosure. In one embodiment, the one or more materials of the receiving antenna can form a coiled antenna, a loop antenna, short dipole antenna, a half wave dipole antenna, a double zepp antenna, an extended double zepp antenna, an antenna one and a half wave dipole, a double dipole antenna, a dipole antenna center, a microstrip antenna, a patch antenna, a stripline antenna, a PCB transmission line antenna, and / or any other appropriate type of antenna as would be appreciated by those skilled in the art and with the benefit of this dissemination. In addition, in one embodiment, the receiving antenna may include a terminal interface. In such a modality, the terminal interface can electrically and / or physically connect the receiving antenna to a receiving circuit, as disclosed in this document. In one embodiment, the terminal interface may include one or more wires, one or more traces of metal, a BNC connector, a terminal connector, an optical connector, or any other appropriate connection interfaces as would be appreciated by those skilled in the art and with the benefit of this disclosure.
[0065] In one embodiment, the receiver 218 further comprises an optional receiver circuit and can be configured to adjust the receiving antenna and / or be sensitive to the presence of the predetermined EM signal from the receiving antenna. For example, the receiving circuit can be configured to define and / or to adjust the resonance of the receiving antenna and to supply an electrical signal (for example, an analog voltage, an analog current) in response to the receipt of the predetermined EM signal. In addition, or alternatively, the receiving circuit can be configured to amplify the electrical signal from the receiving antenna, to filter the electrical signal from the receiving antenna, to drive the actuator 250, and / or any combination of these, as would be appreciated by those skilled in the field. technique and with the benefits of this dissemination. In such an embodiment, the receiving circuit may be in signal communication with the receiving antenna. In one embodiment, the receiving circuit receives an electrical signal from the receiving antenna and generates an output response (for example, an electric current or an electrical voltage). In one embodiment, the receiving circuit can comprise any appropriate configuration, for example, comprising one or more printed circuit boards, one or more integrated circuits (for example, an ASIC), one or more of a discrete circuit, one or more devices active, one or more components of passive devices (for example, a resistor, an inductor, a capacitor), one or more microprocessors, or one or more microcontrollers, one or more wires, an electromechanical interface, a power supply and / or any combination of these. For example, the receiving circuit may comprise a resistor-inductor-capacitor circuit and may configure the receiving antenna to resonate and / or respond at a predetermined frequency. As noted above, the receiving circuit may comprise a simple, unitary or non-distributed component capable of performing the function disclosed in this document; alternatively, the receiving circuit may comprise a plurality of distributed components capable of performing the functions disclosed in this document.
[0066] In one embodiment (for example, in the embodiment of Figure 4, where receiver 218 and driver 250 comprise distributed components) receiver 218 may communicate with driver 250, through a suitable signal channel, for example , through one or more suitable wires. Examples of suitable wires include, but are not limited to, solid core of insulated copper wires, insulated copper wires with cord, unshielded twisted pairs, fiber optic cables, coaxial cables, any other suitable wires as would be appreciated by those skilled in the art in technique, or their combinations.
[0067] In one embodiment, the receiving circuit may comprise a voltage-directed circuit (for example, a transistor power amplifier) configured to produce a voltage signal (for example, an activation signal) for the driver 250 in response to the electrical voltage or electrical current of the receiving antenna. In an alternative embodiment, the receiving circuit may include a switch (for example, an electromechanical relay, one or more of a transistor, one or more of a recording valve) configured for a short physical connection between the actuator 250 and a power source. electronic voltage in response to electrical current or electrical voltage from the receiving antenna.
[0068] In one modality, the receiving circuit can communicate with the driver 250, through an appropriate signaling protocol. Examples of such a signaling protocol include, but are not limited to, an encoded digital signal. Alternatively, in one mode, the receiver circuit can communicate with the driver 250, via an electronic signal (for example, an analog voltage or current signal).
[0069] In one embodiment, the receiver circuit can be configured to provide a digital voltage or current signal to a driver 250 in response to the presence of the predetermined EM signal. For example, in one mode, the receiver circuit can be configured to transition its output from a low voltage signal (for example, about 0V) to a high voltage signal (for example, about, 1.5 V, about 3 V, about 5 V) in response to the presence of the predetermined RF signal. In an alternative embodiment, the receiver circuit can be configured to transition its output from a high voltage signal (for example, about 1.5 V, about 3 V, about 5 V) to a low voltage signal (for example, about 0V) in response to the presence of the predetermined EM signal.
[0070] Additionally, in a modality, the receiver circuit can be configured to operate in "sleep" mode or in low energy consumption mode or, alternatively, in an operational or active mode. The receiving circuit can be configured to enter active mode (for example, to "wake up") in response to a predetermined RF signal, for example, as disclosed in this document. In some embodiments, the actuator 250 may not be coupled to a power source other than that generated by the receiving antenna.
[0071] In one embodiment, the 218 receiver can be powered with electrical energy generated by the receiving antenna. For example, in one embodiment, in response to receiving an EM signal from a receiving antenna (for example a coiled antenna) it can inductively generate an EM field that can be transferred to an electrical current or an electrical voltage (for example, inductive coupling) ) For example, in one embodiment, the EM field can generate an alternating electrical current and the receiver 218 can include a rectifier bridge configured to generate an electrical voltage in response to alternating electrical current that passes through. In such an embodiment, the electrical voltage generated by the rectifier bridge can supply energy to the receiver 218 and / or the driver 250. For example, the generated energy can supply energy in the range of about 3mW to about 0.5 W, alternatively, of about 0.5 to about 1.0 w. In one mode, the energy generated by the antenna may be the only power phone available for the device, which may be sufficient to drive the 250 trigger. In one mode, the energy provided by the receiving antenna may be the only source of energy for the receiver 218 and / or driver 250.
[0072] In an alternative modality, the 218 receiver can receive electrical energy through an energy source. For example, in such an embodiment, the WAVA 200 may additionally comprise an integrated battery, be coupled to a power generation device, be coupled to a power source inside the well, be coupled to a power source outside the well, or any combination of these. In such an embodiment, the power source and / or power generation device can supply power to the receiving circuit 218, the driver 250, and / or combinations thereof, for example, for the purpose of operating the receiver 218, the driver or their combinations. An example of a power source and / or a power generation device is a galvanic cell. In one embodiment, the power source and / or power generating device may be sufficient to power the receiver 218, the actuator 250 or combinations thereof. For example, the power source and / or power generating device can supply power in the range of about 0.5 to about 10 watts, alternatively, from about 0.5 to about 1.0 watts.
[0073] In one embodiment, the actuator 250 can generally be configured to provide selective fluid communication in response to an activation signal (for example, an analog voltage or current). For example, driver 250 may or may not allow fluid to communicate between two or more chambers 220 in response to an activation signal. In one embodiment, at least part of the driver 250 can be positioned adjacent and / or partially to the third chamber part 220c. In such an embodiment, the driver 250 can be configured to provide fluid communication between the third part of the camera 220c and the second part of the camera 220b in response to an activation signal. In one embodiment, the third chamber part 220c may have a pressure below the second chamber part 220b.
[0074] In an embodiment such as that illustrated in Figure 5, the actuator 250 may comprise a piercing member 224, such as a hole punch or needle. In such an embodiment, the perforator can be configured, when activated, to prick, puncture, rupture, pierce, destroy, disintegrate, burn or otherwise cause the actionable member 222 to stop sealing the third portion of chamber 220c . In such an embodiment, the drill may be electrically driven, for example, via an electrically driven motor or an electromagnet. Alternatively, the drill may be propelled or driven by hydraulic means, mechanical means (such as a spring or threaded rod), a chemical reaction, an explosion or any other appropriate means of propulsion in response to the receipt of an activation signal.

For example, the actionable member can comprise a flammable material (for example, a termite) that, when detonated or lit, can burn a hole in the actionable member 222. In one embodiment, the trigger 250 (for example, the punch member 224) it can comprise a flow passage (for example, with a door, with a slit, with surface channels, etc.) to allow hydraulic fluid to pass through it.
[0075] In an alternative embodiment, the actuator 250 may comprise an actionable valve. In such an embodiment, the valve can be integrated into housing 210, for example, by defining at least partially the sliding chamber 220 (for example, defining the third chamber 220c). In such an embodiment, the valve can be active (for example, open) so as to allow fluid communication between the third portion of the chamber 220c and the second portion of the chamber 220b.
[0076] In one embodiment, the actionable member 222 can be configured to contain the hydraulic fluid in the second portion of chamber 220b until a trigger event occurs (for example, an activation signal), as disclosed in this document. For example, in one embodiment, the actionable member 222 can be configured to be minced, pierced, broken, pierced, destroyed, disintegrated, burned or the like, for example, when subjected to a desired force or pressure. In one embodiment, the actionable member 222 can comprise a rupture disc, a rupture plate or the like, which can be formed from an appropriate material. Examples of such suitable materials may include, but are not limited to, metal, ceramic, glass, plastic, composite or combinations thereof.
[0077] In one embodiment, from the destruction of the actionable member 222 (e.g. opening), the hydraulic fluid in the second portion of the chamber 220b may be free to move out of the second portion of the chamber 220b through the passage previously contained in / obstructed by the actionable member 222. For example, in the embodiment of Figure 3B, from the destruction of the actionable member 222, the third portion of the chamber 220c can be configured in such a way that the fluid can be free to flow out from the second portion of the chamber 220b and into the third portion of the chamber 220c. In alternative embodiments, the third portion of the chamber 220c can be configured so that the fluid flows into a secondary chamber (for example, an expansion chamber), from the well tool (for example, inside the well), in the passage flow or combinations thereof.
[0078] Additionally or alternatively, the second portion of chamber 220b can be configured to allow fluid to flow from there at a predetermined or controlled rate. For example, in such an embodiment, an atmospheric chamber can further comprise a fluid meter, fluidic diode, fluidic restrictor or the like. For example, in such an embodiment, the fluid can be emitted from a second portion of the chamber 220b through a fluid opening, for example, a fluid opening that can comprise or be fitted at a fluid pressure and / or a fluid flow rate switching device, such as an injector, or a metering device, such as a fluidic diode. In one embodiment, such an opening can be sized to allow a certain rate of flow or fluid, and thus provide a desired opening time or a delay associated with the flow of fluid leaving the second portion of chamber 220b and, thus, the movement of the sliding member 216. The devices for controlling the fluid flow rate and the methods of using them are disclosed in US Patent Application Pub No. 2011/0036590 kutkhilcclc “U {uVgo cpf OgVjqf hot Ugmekiig c Ygllborg ”rcrc Lkookg T.

In one embodiment, the terminal interface can comprise wire connections, one or more traces of metal, a BNC connector, a terminal connector, an optical connector and / or any other appropriate connection interface, as would be appreciated by someone skilled in the art when viewing this disclosure.
[0082] In one embodiment, the transmitting circuit 310 can be configured to generate an EM signal and to transmit the EM signal through the transmitting antenna. For example, in one embodiment, the transmitting circuit 310 can, in general, be configured to generate an electrical signal (for example, electrical current or electrical voltage), to amplify the electrical signal, to modulate the electrical signal, to filter the signal electrical, to transmit the electrical signal through the transmitting antenna and / or any combination of these, as would be appreciated by someone skilled in the art when viewing this disclosure. In this embodiment, the transmitting circuit 310 may be in signal communication with the transmitting antenna.
[0083] In one embodiment, the transmitting circuit 310 may comprise any appropriate configuration, for example, comprising one or more printed circuit boards, one or more integrated circuits (for example, an ASIC), one or more discrete circuit components, one or more active devices, one or more passive devices (for example, a resistor, an inductor, a capacitor), one or more microprocessors, or one more microcontrollers, one or more wires, one or more electromechanical interfaces, one or more sources of energy and / or any combinations thereof. As noted above, transmitter circuit 310 may comprise a single, unitary or non-distributed component capable of performing the function disclosed in this document; alternatively, the transmitting circuit 310 may comprise a plurality of distributed components capable of performing the functions disclosed in this document.
[0084] For example, in one embodiment, the transmitting circuit 310 may comprise an integrated circuit comprising a crystal oscillator from a coiled transmitting antenna. In such an embodiment, the crystal oscillator can be configured to generate an electrical voltage signal that comprises one or more predetermined frequencies. Additionally, in such an embodiment, the electrical voltage signal can be applied to the coiled transmitting antenna and, in response, the coiled transmitting antenna can generate an EM signal. As disclosed here, the EM signal can be effective to elicit a response from WAVA, in order to "wake up" one or more components of drive system 226, to activate drive system 226, as disclosed in this document, or combinations thereof.
[0085] In one embodiment, the transmitter circuit 310 can be supplied with electrical energy through a power source. For example, in such an embodiment, transmitter 300 may comprise an on-board battery, a power generating device or combinations thereof. In such an embodiment, the power source and / or the power generating device (for example, a battery) can supply power to the transmitting circuit 310, for example, for the purpose of operating the transmitting circuit 310. An example of a power source power and / or power generation device is a Galvanic Cell. In one embodiment, the power source and / or the power generation device may be sufficient to connect the transmitting circuit 310. For example, the power source and / or the power generation device may provide power in the range of approximately 0.5 to approximately 10 watts, alternatively from approximately 0.5 to approximately 1.0 watt.
[0086] One or more modalities of a WAVA 200 and a system comprising one or more of that WAVA 200, having been disclosed, one or more modalities of a wireless drive system method using one or more of the WAVAs 200 (and / or a system comprising that WAVA 200) are disclosed in this document. In one embodiment, such a method can generally comprise the steps of supplying a tubular well column 120 comprising one or more WAVAs 200 in a well 114 that penetrates underground formation 102, optionally isolating adjacent zones from underground formation by passing a transmitter 300 inside the flow passage 121 of the tubular column of well 120, preparing the WAVA 200 for communication of a formation fluid (for example, a hydrocarbon, such as oil and / or gas) and communicating a formation fluid through ports 212 of the WAVA 200. In an additional embodiment, for example, where multiple WAVA 200 are placed inside a well 114, a method of driving a downhole component may further comprise the repetition of the WAVA 200 preparation process for communicating a production fluid and the communication of a production fluid through ports 212 of the WAVA 200 to each of the WAVAs 200.
[0087] Referring to Figure 2, in one embodiment, the method of the wireless drive system comprises positioning or "rolling" a completion column 120 comprising a plurality of WAVA 200a-200i within well 114. For For example, in the form of Figure 2, completion column 120 has a first WAVA 200a, a second WAVA 200b, a third WAVA 200c, a fourth WAVA 200d, a fifth WAVA 200e, a sixth WAVA 200f, a seventh WAVA 200g, an eighth WAVA 200h and a new WAVA 200i. Also in the form of Figure 2, completion column 120 is positioned inside well 114, so that the first WAVA 200a, the second WAVA 200b, the third WAVA 200c, the fourth WAVA 200d, the fifth WAVA 200e, the sixth WAVA 200f, seventh WAVA 200g, eighth WAVA 200h and ninth WAVA 200i can be positioned close and / or substantially adjacent to a first, a second, a third, a fourth, a fifth, a sixth, a seventh , an octave and a ninth underground formation zone 2, 4, 6, 8, 10, 12, 14, 16 and 18, respectively. Note that, although in the form of Figure 2 the tubular column of well 120 comprises nine WAVAs (for example, WAVA 200a-200i), someone skilled in the art, when viewing this disclosure, will appreciate that any appropriate amount of WAVAs 200 can be similarly incorporated into a tubular column, such as the well 120 tubular column, for example, one, two, three, four, five, six, seven, eight or more WAVAs 200. In an alternative embodiment, two or more WAVAs 200 can be positioned close and / or substantially adjacent to a single formation zone, alternatively a WAVA 200 can be positioned adjacent to two or more zones.
[0088] In one embodiment, once the completion column 120 comprising WAVA 200 (for example, WAVA 200a-200i) is positioned in well 114, one or more of the adjacent zones can be isolated and / or the completion column 120 it can be safe within the underground formation 102. For example, in one embodiment, the first zone 2 mode is isolated from relatively more portions of the top of the well 114 (for example, through a first plug 170a), the first zone 2 it can be isolated from the second zone 4 (for example, through a second shutter 170b), the second zone 4 from the third zone 6 (for example, through a third shutter 170c), the third zone 6 of the fourth zone 4 (for example , through a fourth obturator 170d), the fourth zone 8 of relatively more downhole portions of well 114 (e.g., through a fifth obturator 170e) or combinations thereof. In one embodiment, the adjacent zones can be separated by one or more suitable isolation devices from the well. Suitable well isolation devices are generally known to those skilled in the art and include, but are not limited to, shutters, such as mechanical shutters and obtutcfqtgu fklcVáxgku * rqt gzgornq. Uwgllpcekgru ™. eqogtekclogpVg available from Halliburton Energy Services, Inc.), sand plugs, sealant compositions like cement, or combinations thereof. In an alternative embodiment, only a portion of the zones (for example, zones 218) can be isolated, alternatively, the zones can remain non-isolated. Additionally and / or alternatively, a shield column can be secured within the formation, as noted above, for example, by cementation.
[0089] In one embodiment, for example, as shown in Figure 2, the WAVA 200a-200i can be integrated within the completion column 120, for example, so that the WAVA 200 and the completion column 120 comprise a passage of common flow. Thus, a fluid and / or an object introduced in the completion column 120 will be communicated with the WAVA 200.
[0090] In the modality, the WAVA 200 is introduced and / or positioned inside a well 114 in the first configuration, for example, as shown in Figure 3A and in Figure 6A. As disclosed in this document, in the first configuration, the sliding member 216 can be fixed in the first position, thus obstructing fluid communication to / from the flow passage 36 of the WAVA 200 to / from the outside of the WAVA 200 through of the doors 212. In some embodiments, the sliding member 216 can be positioned in a bypass door and a separate flow passage can exist in such a way as to allow production through a flow control device. The first configuration of the completion set comprising the WAVA in the first position can be used during a completion operation and / or during production for any amount of time.
[0091] In a mode in which the well is served by working from the bottom of the well upwards, the first WAVA 200a can be used to be translated into a different configuration. For example, WAVA 200a can be prepared for the communication of a formation fluid (for example, a hydrocarbon, such as oil and / or gas) from the nearby formation zone (s). In one embodiment, the preparation of the WAVA 200 to communicate the formation fluid in general comprises the communication of an EM signal within the flow passage 36 of the WAVA 200 to pass the WAVA 200 from the first configuration to the second configuration.
[0092] In one embodiment, the EM signal can be configured to the WAVA 200 to pass the WAVA 200 from the first configuration to the second configuration, for example, by passing the sliding member 216 from the first position to the second position. In one embodiment, the EM signal can be transmitted by inserting a transmitter (for example, a dart) into the flow passage 36 of completion column 120. In one embodiment, the EM signal can be unique for one or more WAVAs 200 and / or one or more receivers 218 of one or more of the WAVAs 200. For example, a WAVA 200 (for example, the drive system 226 of that well tool) can be configured so that a predetermined EM signal can elicit a response from a specific well tool and / or from the WAVA. For example, the EM signal can be characterized as unique for a specific tool (for example, one or more WAVAs 200a-200i and / or one or more receivers 218). In an additional or alternative mode, a given EM signal can cause a given tool to enter an active mode (for example, wake up in a low energy mode) and / or activate the drive system 226.
[0093] In one embodiment, the EM signal can comprise known characteristics, known frequencies, modulations, data rates, for example, as previously disclosed. The EM signal can be detected by the receiving antenna of one or more receivers 218. In one embodiment, the receiving antenna can communicate with the trigger 250, for example, transmitting a voltage signal through electrical wires in response to the detection of a predetermined EM signal (for example, a frequency, a modulation and / or any other known characteristics of the EM signal).
[0094] In one embodiment, in response to (for example, from) receiving the predetermined EM signal, the drive system 226 can allow the fluid to escape from the second portion of the chamber 220b. For example, in one embodiment, receiver 218 can detect an EM signal within flow passage 36 and receiver 218 can terminate if the detected EM signal is a predetermined EM signal (for example, via inductive coupling). In response to the predetermined EM signal, receiver 218 can communicate an activation signal (for example, electrical current) to driver 250, thereby causing driver 250 to stop sealing the second portion of chamber 200b and providing the fluid communication with the fluid contained therein. Since the fluid flows from the second portion of the chamber 220b, the fluid will no longer retain the sliding member 216 in its first position and the sliding member 216 can move from the first position to the second position. For example, the sliding member 216 can move from the first position to the second position as a result of a fluid pressure applied to the first portion of the chamber 220a. In one embodiment, the sliding member 216 can move from the first position to the second position due to a differential in the surface area of the upward facing surfaces, which are fluidly exposed to the first portion of the chamber 220a and in the area surface area of the downward facing surfaces, which are fluidly exposed to the second portion of chamber 220b. In one embodiment, the transition from sliding member 216 from the first position to the second position can open the WAVA to flow by clearing the internal port 212b, thereby providing a fluid communication route between the internal port 212b and the outer port port 212a for fluid flow. In one embodiment, the transition of the sliding member 216 from the first position to the second position can open a flow passage through a flow restriction by clearing the inner door 212d, thereby providing a fluid communication route between the outer door 212c and inner port 212d for fluid flow. In one embodiment, the process of preparing the WAVA 200 for the communication of a fluid can further comprise the actuation (for example, opening) of one or more bypass valves 416 of the WAVA 200. In such an embodiment, one or more of the valves bypass 416 of the WAVA 200 can be triggered (for example, through electric current) and can provide a fluid communication route between external port 212c and flow passage 36 through bypass port 410. Since the WAVA 200 has been configured for the communication of a formation fluid (for example, a hydrocarbon, such as oil and / or gas), for example, when the well tool (for example, the first WAVA 200a) has moved to the second configuration, fluid communication can be established between the first forming zone 2 and the flow passage 36 through the unobstructed ports 212 of the first WAVA 200a.
[0095] In one embodiment, the process of preparing the WAVA 200 for communicating a fluid (for example, a production fluid) via an EM signal and communicating a production fluid through ports 212 of the WAVA 200 to the zone close to that WAVA 200 can be repeated in relation to one or more of the well tools (for example, the first WAVA 200a, the second WAVA 200b, the third WAVA 200c, the fourth WAVA 200d, the fifth WAVA 200e, the sixth WAVA 200f, the seventh WAVA 200g, the eighth WAVA 200h and / or the ninth WAVA 200i). For example, in one embodiment, the WAVA preparation process can be repeated for the first WAVA 200a and can trigger (for example, open) one or more additional ports 212 for fluid communication. In an additional or alternative embodiment, one or more WAVAs 200 (for example, the second WAVA 200b) can be prepared for the communication of a fluid (for example, a fluid production).
[0096] When one or more of the well tools are in the well, the transmitter can be used to drive only a single WAVA or a plurality of WAVAs. For example, the transmitter can transmit a single frequency that is inductively coupled to a specific WAVA (for example, the first WAVA 200a), thus providing power to drive the specific WAVA. In order to drive another WAVA, a second transmitter can be arranged in the well to drive one or more of the remaining WAVAs (for example, the second WAVA 200b, the third WAVA 200c, the fourth WAVA 200d, the fifth WAVA 200e, the sixth WAVA 200f, the seventh WAVA 200g, the eighth WAVA 200h and / or the ninth WAVA 200i). This process can be repeated to trigger the desired number of WAVAs. In one embodiment, the single frequency transmitted by the transmitter can trigger a plurality of WAVAs. For example, two or more of the WAVAs can be configured to trigger based on the same frequency as the EM signal. In this modality, a transmitter can be used to activate the applicable plurality of WAVAs in a single passage along the well.
[0097] In one embodiment, a transmitter can transmit a plurality of frequencies, which can trigger a plurality of WAVAs. For example, the transmitter can transmit a plurality of frequencies, with each frequency being inductively coupled to one or more WAVAs (for example, one or more of the first WAVA 200a, the second WAVA 200b, the third WAVA 200c, the fourth WAVA 200d, the fifth WAVA 200e, the sixth WAVA 200f, the seventh WAVA 200g, the eighth WAVA 200h or the ninth WAVA 200i). The receivers associated with each WAVA can be configured to inductively couple with one of the plurality of frequencies, thus allowing any desired combination of WAVAs to be triggered by a transmitter passed through the well. As another example, when a plurality of WAVAs are present in a single location (for example, distributed circumferentially around a glove), the transmitter can be configured to trigger one or more of the WAVAs, without necessarily triggering all the WAVAs. This can allow for a selective configuration of the flow passage at a given location.
[0098] In some modalities, the transmitter can transmit different frequencies at different periods and / or locations within the well. In this mode, the transmitter can transmit one or more frequencies as they pass through the well. The transmitter can vary the transmission of one or more of the frequencies based on time, depth, pressure, temperature or the like to selectively trigger one or more of the WAVAs. The transmitter's ability to transmit a single signal, a plurality of signals or signals that change during passage through the well can allow the WAVA to be selectively reconfigured during use, with some zones being changed, while others are kept in their settings original or subsequent ones.
