Abstract: A shear valve utilizing an elastically responsive unibody seal member in operation. The unibody seal member is of unitary constriction and in terms of adjacent ends thereof and an energizing member disposed therebetween. Thus, governing of fluid flow through the metal valve may be achieved without undue concern over high pressure differentials, for example in a downhole environment. Further, the unitary construction of the seal member alleviates concern over mismatching tolerances and/or dimensions for separately assembled miniaturized components of the valve.

Abstract: A self-seeking plug for deployment in a hydraulic line with a leak therein. The plug is configured for circulation through the line and to a resting location adjacently below or past the location of the leak in the line. As a result, the location of the leak may be identified, for example with reference to a tether running between the resting location and the site of deployment. Thus, line repair may more readily ensue. Additionally, and/or alternatively, sealing repair may ensue by way of sealing element(s) outfitted on the plug. Such may or may not be accompanied by an exposable bypass channel through the plug for sake of full hydraulic restoration of the line.
