摘要： A flow control device for use in a wellbore which has a nozzle with an output to provide a jet of fluid and a structure proximate the nozzle. The structure is positioned a set distance away from the output of the nozzle, where the set distance is greater than a length of a potential core of the jet of fluid.

摘要： A wellhead seal assembly for sealing between first and second pipe members comprises an annular elastomeric body having, in cross-section, a generally rectangular shape comprising a first flat radial surface, a second flat radial surface, an inner circumferential surface and an outer circumferential surface; said inner circumferential surface comprises a generally convex portion that extends from an imaginary plane connecting the inner circumferential edge of each of said first radial surface and said second radial surface; said seal assembly further comprises at least one annular, non-metallic spring member in said elastomeric body positioned generally tangentially to the intersection of either of said radial surfaces with said inner circumferential surface.

摘要： A technique is provided to control a downhole tool in a well. An indexer is used to adjust a downhole tool to specific positions on a plurality of positions. The indexer is actuated between settings via control fluid input. The indexer is designed such that a unique amount of control fluid is used for actuation of the indexer to each specific setting.

摘要： An apparatus that is usable with a well includes a tool and a shroud. The tool is to be disposed in a wellbore and includes an opening to inject fluid into the well. The shroud at least partially surrounds the tool to eccentrically dispose the tool with respect to a longitudinal axis of the wellbore.
