摘要： A valve assembly for hydrocarbon wells comprises a first valve (e.g., a conventional gate valve) and a second valve (e.g., a hydraulically operated, fail safe check valve). The second valve provides an alternative to the pressure barrier conventionally formed by a downhole annulus safety valve. It is installable/retrievable through the first valve using a tool of the type used for installation of surface wellhead VR (valve replacement) plugs.

摘要： The present invention generally provides a gas operated pump having a removable and insertable valve. In one aspect, the invention includes a pump housing having a fluid path for pressurized gas and a second fluid path for exhaust gas. The fluid paths are completed when the valve is inserted into a longitudinal bore formed in the housing.

摘要： A reciprocating pump dump valve and methods of use for utilization in the hydrocarbon industry. The device is preferably used with barrel pumps although it may be used with tubing pumps. The device is positioned at the bottom of the wellbore immediately above the stinger and immediately below the standing valve and allows for complete dumping of the hydrostatic head in the production tubing whenever the tubing must be pulled.

摘要： The flapper valve assembly can be used in series to provide collapsible closures in a drill pipe. Thus, when work strings are withdrawn through the flapper valve, it will close in a conventional manner. However, when the work string must be reinserted through the closed flapper, a collar holding the flapper in its closed position can be sheared from its position within the assembly housing.

摘要： A multi-cycle circulating sub apparatus having a control member for controlling the movement of a sleeve between a first or closed position and a second or open position. The control member is slidably mounted in a body and is moveable by fluid pressure in the body in a first axial direction relative to the body. The control member also has a spring biasing the control member in an opposite axial direction of the body. A pin is secured to either the body or the control member. A central groove, in which a portion of the pin is received, is formed in the other of the body or control member. The central groove is shaped to limit axial displacement of the control member in response to pressure variations in the body such that only after a predetermined number of movements of the control member to a first limit position is the control member able to move to a second limit position to displace the sleeve into the second position. The apparatus may also be reset many times while remaining in a downhole position.

摘要： A reciprocating pump vent-dump and methods of use for utilization in the hydrocarbon industry. The device is preferably used with barrel pumps although it may be used with tubing pumps. The device is positioned at the bottom of the wellbore immediately above the stinger and immediately below above the standing valve and comprises a sliding piston within an outer housing. The device may be opened pulling upwards on the pump drive mechanism thereby allowing fluid within the production tubing to drain back into the formation as long as the pump drive mechanism is held up. The device closes when the pump is returned to normal operation.
