    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, a partial view of an exemplary embodiment of a sensor assembly 5 in accordance with the disclosure is shown in Fig. I and is designated generally by reference character 100. Other embodiments of sensor assemblies in accordance with the disclosure, or aspects thereof, are provided in Figs. 2-17, as will be described. The systems and methods described herein can be used for deployment of downhole sensors, ¢.g., for initial placement in new well bores or existing well bores, replacement and/or upgrades in existing well bores, and the like. The sensor assembly 100 includes a patch 102 with a wall 104 configured to be seated in a well casing 106. A sensor 108 is mounted to the wall 104 of the patch 102, The wall 104 of the patch 102 is expandable from an unexpanded diameter for traversing through the well casing 106 as shown in Fig. 1, to an expanded diameter, as shown in Fig. 2, for seating against the inner 18 surface 110 of the will casing 106 that js within an annølus 101 of a well in an earth formation 103, With reference to Figs. 3-4, the wall 104 of the patch 102 includes an intemally trussed expandable structure, which is shown in Fig. 3 unexpanded and in Fig. 4 expanded. The expansion can be accomplished by releasing the patch 102 from a compressed state to allow it to expand, by using a tool to mechanically press outward on the wall 104 of the patch 102, or the like, As shown in Figs. 3-4, the sensor 108 is affixed or mounted to a portion of the wall 104 of the patch 102 that is aligned between the apertures 112, allowing the sensor 108 to remain affixed to the wall 104 regardless of whether the wall 104 is an expanded or unexpanded state. It is also contemplated that the sensor can be placed on the interior of the surface or within the wall
    DK 2020 70559 A1 6 of the expanded structure. Those skilled in the art will readily appreciate that any other suitable type of expandable wall 104 can be used without departing from the scope of this disclosure. Other examples of expandable walls include a bendable corrugated expandable wall 204 of patch 202, which includes a sensor 108 mounted thereto as shown in Figs 5 and 6 in unexpanded and expanded states, respectively, a bendable c-ring wall 304 of patch 300 with a sensor 108 mounted thereto as shown in Figs. 7 and 8 in unexpanded and expanded states, respectively, and a wall 404 with a stretchable structure of a patch 400 with a sensor 108 mounted thereto as shown in Figs. 9 and 10 in unexpanded and expanded states, respectively, It is also contemplated that the sensor 108 can be integral with the patch 102, e.g., with the wall 104 ofthe patch 102.
    Although the wellbore is shown as a cased hole, those skilled in the art will readily appreciate that the sensor assembly 100 can be expanded to fit within production tubing or within an uncased open hole section. In all of these cases, the sensor assembly 100 can be installed on the interior wall of a portion of the wellbore. The axis of the sensor assembly 100 is 13 substantially parallel to the axis of the wellbore.
    With reference again to Fig, 2, the wall 104 of the patch 102, when affixed to the inner surface 110 of the well casing 106, defines a central passage 114 therethrough configured to allow passage of downhole tools therethrough. The drift diameter of a well casing is the maximum diameter that at downhole tool can have and still pass through the well casing. In Fig.
    2, the diameter of the central passage 114 must be large enough to clear or provide an intended drift diameter, which in turn means that the well casing 106 must have a large enough inner diameter to accommodate the radial thickness of patch 102 and sensor 108 and still allow the central passage 114 to be equal to or larger than the intended drift diameter. As shown in Fig. 3,
    DK 2020 70559 A1 7 the well casing 106 can include an expanded diameter portion 116 with an inner diameter D lager than an inner diameter d of portions 118 and 120 of the well casing 106 uphole and downhole from the expanded diameter portion 116. With the patch 102 and sensor 108 seated within the expanded diameter portion 116, the portions 118 and 120 of the well casing 106 can have an inner diameter as small as the intended drift diameter, and the central passage 114 of the patch 102 can still have a diameter equal to or greater than the intended drift diameter without needing the entire well casing 106 to have a larger interior diameter than the intended drift diameter, The expanded diameter portion 116 can allow for a thicker patch 102 and/or sensor 108 while still maintaining a given drift diameter.
    The sensor 108 can be a passive sensor, e.g., such as a sensor that includes a tracer configured to release a chemical, It is also contemplated that the sensor 108 can be an active sensor, €.8., such as a sensor that includes an electrically powered transducer for measuring pressure, temperature, flow rate, flow composition, vibration, acoustics, permeability and/or the like. As indicated by the wireless wave lines in Fig. 2, the sensor 108 can be configured to be 13 coupled to electronics and/or wireless telemetry. For example, in Fig. 2, the sensor 108 is wirelessly connected to communicate data to and/or from a surface system 128. The sensor 108 can include an internal power source 109, such as a battery or a turbine generator, however it is also contemplated that the sensor 108 can receive power, e.g. inductively from the well casing 106, as described below.
    With reference now to Fig. 12, the well casing 106 can include a coil 122 (or multiple coils 122) wound circumferentially around the wall 124 thereof, wherein the coil 122 is electrically connected to a line 126 for communication and/or power. Line 126 can be an optical line that provides a data connection but not power, or can be an electrical line that provides data
    DK 2020 70559 A1 8 and/or power connectivity. The coil 122 is inductively connected to the sensor 108 to power the sensor 108 and/or for data communication between the sensor 108 and systems up well such as the surface system 128 shown in Fig. I. It is also contemplated that capacitive couplings, wet connects, or any other suitable connection can be made between the sensor 108 and the coil 122. As shown in Figs. 13 and 14, the well casing can include multiple small diameter portions 118, 120, and 130 and multiple expanded diameter portions 116. In Fig. 13, only the lefi most expanded diameter portion 116 of the well casing 106 includes a coil 122, and the right most expanded diameter portion 116 does not include a coil, In Fig. 14, both ofthe expanded diameter portions 116 include a respective coil 122, and the two coils 122 are connected together by a line 126. Each of the expanded diameter portions 116 in Fig. 14 is a powered joint, and those skilled in the art will readily appreciate that any suitable number of such powered joints can be included in a well casing 106. The powered joints can be hard wired with little or no electronics and thus can be made to be long lived.
    With continued reference to Figs. 13 and 14, there can be multiple patches 102 with 13 respective sensors 108 seated within the well casing 106. Fig. 13 shows six patches 102 with respective sensors 108, and Fig, 14 shows two patches with respective sensors 108, however those skilled in the art will readily appreciate that any suitable number of patches 106 and sensors 108 can be used without departing from the scope of this disclosure. The assembly 100 can include at least one distributed sensor 108 having sensor components 107 operatively connected to each other but physically spaced apart from one another. For example, in Fig, 14 the sensor 108 can optionally include two separate sensor components 107 (one of which is shown in broken lines) circumferentially spaced apart from one another physically, but connected together wirelessly or by wiring to function together, For example, one of the sensor
    DK 2020 70559 A1 9 components 107 can include power components and processing components, and the other sensor component 107 can include transducer connected by wire or wirelessly to the power and processing components. It is also contemplated that two or more sensor components 107 of a sensor 108 can be separated along a longitudinal axis A of the well casing 106 as shown in Fig.
    13 where three sensor components 107 of a single sensor 108 in the portion 130 of the well casing 106 are identified. It is also contemplated that distributed sensor components 107 can be both axially distributed as shown in Fig. 13 and circumferentially distributed as shown in Fig. 4.
    Fig. 13 demonstrates multiple configurations that can be used. For example, the two sensors 108 in the left most enlarged diameter portion 116 of Fig. 13 can be larger sized (radially thicker) sensors/transmitters/receivers powered by the coil 122, the three sensors 108 in the smaller diameter portion 130 can be passive or battery powered sensors of a smaller size (radially thinner) than those in the expanded diameter portions 116, and the sensor 108 in the right most expanded diameter portion 116 can be a large sized (radially thicker) passive or battery powered sensor.
    With reference now to Fig. 15, the patch 102 can be seated in the well casing 106 proximate an aperture 132 through the well casing 106 that places an interior space 134 of the well casing 106 in fluid communication with a well bore annulus 101 exterior of the well casing
    106. The sensor 108 can therefore be configured to monitor annulus conditions 101 from within the well casing 106 by contact with fluids flowed into the interior space 134 from the annulus
    101.
    With reference now to Fig. 16, the well casing 106 can include a well tool 136 such as a choke, valve, or an inflow control device (ICD) operatively connected to the sensor 108, wherein the sensor 108 is configured to provide control input to the well tool 136, e.g. based on a value
    DK 2020 70559 A1 10 from a transducer of sensor 108. For example, a value from a PH transducer in sensor 108 can be used to control actuation of a valve. As shown in Fig. 17, when the sensor 108 of Fig. 16 fails due to passage of its useful life time, is preempted by an upgraded version, or needs to be replaced for any other suitable reason, a new sensor 108 can be deployed and seated with a new patch 102 (e.g., the lower most patch 102 and sensor 108 in Fig. 17) without necessitating removal of the original sensor 108 (the upper most sensor 108 in Fig. 17). For example, if an upgraded version of the transducer, controller, and/or logic for controlling the tool 136 is available, the new sensor 108 can be deployed into position and the original sensor 108 can be deactivated, e.g., by a signal from line 126 and coil 122 and/or by a signal from the new sensor
    108. This facilitates expansion and/or improvement of the functionality of the tool 136 relative to traditional techniques.
    Using systems and methods as disclosed herein, it is not necessary to retrieve old or dead sensors to deploy new sensors, and the number of sensors is not limited to a number of sensor receptacles within a well casing, for example.
