Abstract: A subsurface safety valve having a valve member with a pressure equalizing mechanism is provided. The valve member includes a bore therethrough for receiving an equalizing plug. A beam is attached to the upper surface of the valve member for transferring downward motion of a flow tube to unseat the equalizing plug, and thereby establish fluid communication through the valve member prior to the opening of the valve member. A retention member is attached to the lower surface of the valve member to upwardly bias the equalizing plug within the plug bore of the valve member.

Abstract: In a broad aspect, the invention relates to an improved downstop seal for use with a rod-piston actuator of a surface controlled subsurface safety valve, wherein the rod-piston actuator has a beveled shoulder formed thereon. The improved downstop seal has a resilient, primary, sealing member having a beveled sealing surface to matingly engage with a portion of the beveled shoulder of the rod-piston actuator; and further has a non-resilient, secondary, sealing member having a beveled sealing surface to matingly engage with a portion of the beveled shoulder of the rod-piston actuator.

Abstract: A subsurface safety valve has a tubular valve housing, a valve closure member movable between an open and a closed position, an axially shiftable flow tube for opening the valve closure member, a spring for biasing the flow tube to a closed position, a piston and cylinder assembly to move the flow tube to an open position, and a plug inserted within an opening in the valve housing. This opening is in fluid communication with the piston and cylinder assembly. The plug is adapted to be displaced from the opening to lock out the safety valve, and to establish secondary hydraulic fluid communication with an interior of the safety valve in order to operate secondary tools, such as wireline set secondary valves, inserted into the locked out safety valve.

Abstract: An injection valve for use in a well having a valve closure element positioned below a valve seat moving between an open position to a closed position on the valve seat for blocking off upward flow through the bore, but allowing downward flow. A flow tube is telescopically movable in the housing for controlling the movement of the valve closure member and a piston is movable in the housing and connected to the flow tube and exposed to fluid in the bore. An upwardly facing shoulder on the flow tube receives a retrievable orifice member for providing a force for fully opening the valve when fluid is injected downwardly through the bore. A retrievable lockout sleeve is provided to lock the valve open when the retrievable orifice is removed.

Abstract: A dump and kill valve for use in a sidepocket having a main bore, a sidepocket in communication with the main bore with ports between the sidepocket and the outside of the mandrel and a shoulder above the pocket. The valve includes a body having a no-go shoulder with an upper first and a lower second seal spaced apart and positioned on the body sealing in the pocket on opposite sides of the port for initially blocking fluid flow. One of the seals is releasably connected to the body and is movable relative to the body upwardly in response to fluid pressure for opening communication between the ports and the main bore. Latch means may be provided between the movable seal and the body for latching the movable seal after opening and the setting tool may include a releasable seal holding shoulder for preventing premature movement of the movable seal.

Abstract: First and second members each having a first side shape for coacting with and secured longitudinally to the outside of a tubular member in a parallel spaced relationship for enclosing a portion of a well control line.

A measuring instrument support is attached to the body by a shock absorber. Locking dogs are radially and longitudinally movable in the body. A dog expander sleeve includes a recess for allowing the dogs to retract and includes a shoulder for locking the dogs outwardly. A locking spring urges the dogs downwardly onto the sleeve shoulder but allows the dogs to move upwardly into alignment with the sleeve recess. A releasing spring acts on the expander sleeve for urging the sleeve upwardly for moving the sleeve shoulder under the dogs but allows the dogs to retract into the sleeve recess on downward movement of the sleeve relative to the body. The body may include pressure equalizing ports and a pressure prong releasably positioned in the body and initially blocking the port.
