Abstract: Systems and methods for enabling communication in a downhole power and communications system installed in a well, where one or more components of a wired backbone of the system have failed. Equipment positioned at the surface of a well is connected to a wired power and communication backbone that has one or more conductors and one or more nodes with standardized interfaces that enable downhole devices to be interchangeably connected to the wired backbone. When the wired backbone has failed at one or more points, preventing wired communications between the surface equipment and one or more downhole devices installed at the nodes, one or more wireless-enabled modules are installed at corresponding nodes of the wired backbone to establish wireless channels that bridge the failed portion of the wired backbone and thereby enable communication between the surface equipment and the downhole devices.

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: An apparatus for applying a magnetic pressure to a work piece includes an inductor configured to be disposed in proximity to the work piece and a controller electrically connected to the inductor and configured to control a supply of electrical power in order to output a first voltage over a selected frequency range to determine a frequency that provides a maximum current or a frequency that provides a current within a selected range of the maximum current to the inductor.
