Abstract: A downhole sensor includes a sensor housing with one or more of a pressure sensor or a temperature sensor. A cable segment having a conductor is coupled to the sensor housing. A spacer or retention element is coupled to or secured to at least a portion of the conductor at a location proximate an interface between the cable segment and the sensor housing. Downhole sensor arrays include such sensor housings. Methods relate to forming such sensor arrays.

Abstract: Downhole distributed pressure sensor arrays include sensor housings each comprising at least one pressure sensor in a pressure housing. Downhole pressure sensors include a housing, at least one pressure sensor in a pressure housing portion of the housing, and at least one isolation element positioned at an outer wall of the housing.

Downhole pressure sensors include a housing, at least one pressure sensor in a pressure housing portion of the housing, and at least one isolation element positioned at an outer wall of the housing.

Abstract: Transducer assemblies may include a sensor and a housing including a pass-through portion comprising at least one aperture in a portion of the housing extending along a longitudinal axis of the housing and the sensor. Methods of forming transducer assemblies may include welding a first housing section of the transducer assembly to a second housing portion of the transducer assembly and forming at least one aperture in the first housing section extending along a longitudinal axis of the transducer assembly, along a chamber for holding a sensor, and through the weld.

Abstract: A method of forming a conditioned isolation element for a sensor assembly comprises subjecting a preformed isolation element structure to at least one thermal annealing process to form a conditioned isolation element structure substantially less susceptible to at least one of hydrogen permeation, hydrogen-based embrittlement, and hydrogen-based stress-cracking. Conditioned isolation elements and sensor assemblies are also described.

Abstract: A downhole sensor array includes sensor housings, and each sensor housing contains one or more of a pressure sensor and a temperature sensor. Cable segments connect the sensor housings. A weld joint bonds a sensor housing to a jacket of a cable segment, and a conductor of the cable segment and the jacket of the cable segment may be separated by a void proximate the weld joint. Methods relate to forming such sensor arrays.
