Abstract: Embodiments are directed towards a lift system for extracting a fluid from a well. The system may include a production tube and at least one bladder located inside a pump barrel which is connected to the production tube. The bladder may include a top connector configured to receive a concentric tubing. The lift system may further include a compression system connected to the concentric tubing. The compression system may be configured to provide a compressed gas through the concentric tubing to the at least one bladder.

Abstract: A system includes a valve housing with a port formed in a wall of the housing, a rotation sleeve disposed in the valve housing, an orienting sleeve with an orienting feature disposed in and fixed to the valve housing, and a shifter. The rotation sleeve is rotatable relative to the valve housing and includes a port formed therethrough. The shifter includes engagement features disposed a distance from each other along a length of the shifter and a rotational distance from each other about a circumference of the shifter. The engagement features are receivable into corresponding features of the orienting sleeve and the rotation sleeve to rotate the rotation sleeve relative to the valve housing as the shifter travels through the valve housing. The system may be used to selectively manipulate any number of valves in downhole equipment.

Abstract: A retrievable Electrical Submersible Pump (ESP) and electrical motor for driving the ESP are positioned in a tubing string in the wellbore and, when desired, retrieved back to the surface. The ESP and motor are on an insertion string and can be lowered using wireline, coiled tubing, and standard running and setting tools. The method eliminates the need to retrieve the tubing string to repair, replace, or service the ESP and motor.

Abstract: A retrievable Electrical Submersible Pump (ESP) and electrical motor for driving the ESP are positioned in a tubing string in the well-bore and, when desired, retrieved back to the surface. The ESP and motor are on an insertion string and can be lowered using wireline, coiled tubing, and standard running and setting tools. The method eliminates the need to retrieve the tubing string to repair, replace, or service the ESP and motor.

Abstract: A packer (80) for establishing sealing engagement with a surface disposed in a wellbore includes a packer mandrel (90) and a seal assembly (100, 102, 104) slidably disposed about the packer mandrel (90). The seal assembly (100, 102, 104) has a running position and a radially expanded sealing position. A piston (122) is slidably disposed about the packer mandrel (90) and operably associated with the seal assembly (100, 102, 104). A release assembly 145 is disposed about the packer mandrel (90) and is releasably coupled to the piston (122) such that actuation of the release assembly (145) decouples the release assembly (145) from the piston (122) allowing the piston (122) to shift longitudinally relative to the packer mandrel (90) to operate the seal assembly (100, 102, 104) from the running position to the radially expanded sealing position, thereby setting the packer (80).

Abstract: Packer assemblies capable of providing desired load-bearing performance and of being retrieved from a bore in a subterranean formation are described. A packer assembly can include a wedge that can respond to a force in a downhole direction by un-supporting the slip. The unsupported slip is configured to disengage from a casing string, allowing the packer assembly to be removed from the bore. The wedge can include a collet to allow the wedge to separate from the slip to prevent slip re-setting.
