Abstract: An compact instrumented downhole coupling that includes a carrier and a set of sensors and electronics that are installed within the carrier. The carrier is a tubular structure having couplings at each end and a bore extending through the carrier from the first end to the second end, forming a carrier wall between the bore and the exterior surface of the carrier. The bore and couplings are offset from a central axis of the carrier (the axis of the cylindrical outer surface of the carrier), resulting in a thicker portion of the carrier wall on one side of the carrier. Cavities are formed (e.g., by drilling holes) within the thicker portion of the carrier wall. One or more sensors and corresponding electronics are then positioned within the cavities, so that the carrier wall itself forms a housing for the sensors and electronics.

Abstract: Systems and methods for communicating between surface equipment and a downhole tool installed in a well. First and second toroidal transformers are positioned around an inner one of a pair of coaxial structural members of a well completion (e.g., a pump rod and tubular, or a tubular and a well casing) which are electrically coupled to form an electrical circuit. A transmitter generates a data signal which is applied to the first toroidal transformer, causing a corresponding electrical current to be induced in the circuit, which then induces the data signal on the second toroidal transformer. A receiver coupled to the second toroidal transformer receives the data signal induced on the second toroidal transformer. The transmitter and receiver may be components of transceivers that may communicate bidirectionally. Additional toroidal coils and transceiver may be provided to communicate with equipment at additional locations in the well.

Abstract: Systems and methods for wireless power transmission in a well, wherein first and second structural members of a well completion are electrically connected to form an electrical circuit, with first and second toroidal transformers positioned around the second structural member at different axial locations. A power source coupled to the first toroidal transformer is configured to generate an output voltage which is applied to the first toroidal transformer, inducing a corresponding electrical current in the electrical circuit. This in turn induces a second voltage on the second toroidal transformer, which is provided to a downhole tool. The tool may include conditioning circuitry, which rectifies the received power and charges a battery. The downhole electric tool is then operated using the received power.
