An electric gas lift valve may comprise a casing, gas lift mandrel, one or more annulus, a tubing, a venturi sleeve, a needle, a governor, anti-rotational key, a rotational (rotating) bellow, a gearbox housing that houses a gearbox, an electrical motor, and an encoder. The bellow therefore allows the electrical motor, encoder and gearbox to be hermetically sealed against the external environment. Bellows that absorb torsion are provided. A bellow configured to absorb torsion comprising: a plurality of convolutions bent following a circular trajectory such that a start edge of a first convolution of the plurality of convolutions coincides with a finish edge of a last convolution of the plurality of convolutions, the start edge of the first convolution coupled to the finish edge of the last convolution.

Single actuated rotational electric gas lift valve

Systems and methods for wireless deployment of electrical lower completions are provided. A wet disconnect tool-running tool includes a battery and telemetry section, and electronics and sensors section, and a pressure compensator and control lines section.

Wireless electrical lower completion deployment

A technique facilitates actuation of a downhole device, such as an isolation valve. According to an embodiment, the downhole device may be in the form of an isolation valve member, e.g. a ball valve element, actuated between positions by a mechanical section which may comprise a shifting linkage. Actuation of the mechanical section, and thus actuation of the isolation valve member, is achieved by a trip saver section controlled according to a pressure signature which may be applied from a suitable location, e.g. from the surface. The trip saver section comprises a housing having an internal actuation piston coupled with the mechanical section. The trip saver section further comprises a pilot piston and a plurality of chambers formed in a wall of the housing and arranged to enable shifting of the actuation piston in response to a predetermined series of pressure pulses or other suitable pressure signature.

System and methodology for actuating a downhole device

An isolation valve system includes a well string having an isolation valve including a ball rotatably mounted to a pair of inserts for rotation about a fixed axis, an arm coupled to the ball at a position offset from the fixed axis, and a mandrel connected to an actuation end of the arm, the mandrel and the actuation end of the arm being disposed uphole of the ball. Via the actuation end of the arm, the mandrel forces rotation of the ball from a closed position to an open position by moving in a linear direction away from the ball, which allows flow of fluid along a through hole of the ball.
