    摘要： 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.

    摘要： A pressure control valve for downhole treatment operations includes a valve body including an inlet, an outlet, and a valve seat. A valve assembly is arranged in the valve body. The valve assembly includes a valve member selectively positionable on the valve seat to control fluid flow through the valve body. A piston assembly including a piston and a control fluid inlet is arranged in the valve body. The piston is operatively connected to the valve assembly. The piston is operable to bias the valve member toward a closed configuration upon exposure to a control fluid.

    摘要： A fluid injection valve comprising: a valve body including a first end having a first opening, a second end having a second opening, an outer surface and an inner surface defining a fluid pathway extending between the first end and the second end; a seat arranged along the fluid pathway; a restriction device selectively abutting the seat; a biasing member arranged in the fluid pathway abutting the restriction device; urging the restriction device against the seat; a biasing element having a biasing force urging the biasing member against the restriction device; and a magnet functionally connected to the biasing element, the magnet selectively forcing the biasing member axially outwardly of the restriction device against the biasing force.
