Abstract: A reciprocating drive apparatus (10) comprises a housing (12) and a mandrel (14), configurable to be rotated relative to each other. The apparatus further comprises a reciprocating piston (16) mounted within a piston housing (18) to define a piston chamber (20a), wherein the piston is moveable in reverse first and second axial directions (A,B), and a rotary valve assembly (24) comprising a valve inlet (28) for communicating with a pressure region (P) and a valve exhaust (30) for communicating with an exhaust region (E). The rotary valve assembly (24) is cyclically reconfigured between a pressure configuration and an exhaust configuration. In the pressure configuration the piston chamber (20a) is in pressure communication with the valve inlet (28) and isolated from the valve exhaust (30) and in the exhaust configuration the piston chamber (20a) is isolated from the valve inlet (28) and in pressure communication with the valve exhaust (30).

Abstract: A safety valve includes a housing having a bore, a flow tube, and a valve closure member. The flow tube resides in the bore, is configured to move telescopically within the bore, and is adapted to shift the valve closure member between a closed position and an open position. The safety valve also includes an annular section between an inner surface of the housing and an outer surface of the flow tube, and means for preventing fluid flowing through the bore from entering the annular section.

Abstract: An apparatus for deploying a pump system includes an inflatable annular seal (16) disposed on an exterior of a pump system housing. The annular seal defines a first flow path (10A) and a second flow path (10B) in a wellbore tubular when the annular seal is inflated. A pump (14) has a fluid inlet (14A) disposed in the first flow path when the annular seal is inflated and a fluid outlet (14B) disposed in the second flow path. A valve (60) is operable to direct discharge from the pump into an inflation line (17) fluidly coupled to the annular seal (16) when the valve (60) is in a first position or to surface when the valve is in a second position. The valve is operable between the first and second positions by applying and releasing upward tension on the pump housing or applying fluid pressure to the valve.

Abstract: An isolation valve system, method, and apparatus are provided that can isolate a wellbore and prevent fluids from exiting the well and prevent seawater from entering the well. The system can be a two-part design in some embodiments where a shear sub is selectively interconnected to a body via shearing screws. A sufficient force on the shear sub destroys the shearing screws and the shear sub is removed from the body. This movement rotates an actuator on the body, which in turn rotates a valve in the body to provide the isolating function during routine operation of a wellbore or during an emergency.

Abstract: A downhole flow control system utilizes a tubing pressure operated valve to selectively open and close fluid flow across the system. The tubing pressure operated valve includes a piston responsive to tubing pressure, and a valve element responsive to piston movement. The valve element can be moved rotationally, longitudinally, or both, in response to the piston movement. The valve is movable between a closed and at least one open position. The piston and valve elements can be releasably attachable, such as by a one-way ratchet. The valve element can be a rotating valve operable by a J-slot mechanism to rotate to multiple positions in response to movement of the piston element.

Abstract: A flow control assembly for regulating fluid flow in a wellbore is disclosed. A remote-open ICD is opened in response to swelling of a swellable actuator. The swellable actuator can move a flow regulator radially, circumferentially, etc., such that flow is allowed through the regulator. Alternately, the swellable actuator can move one or more valve members to an open position thereby allowing fluid to flow across the valve and to the flow regulator. The swellable actuator can be swelled in response to introduction of chemicals or heat. A guide mechanism can be used to control swelling of the actuator or movement of the regulator device or valve member.
