A shifting tool having a release mechanism of predictable deforming radial character. The tool may be utilized for activating any of a variety of different types of downhole actuators. Once more, due to the controlled and predictable manner of deformation employed in the release mechanism, load pulls directed at the actuator may be significant without undue concern over unintended or uncontrolled tool breakage. So, for example, a stuck actuator arm engaged with the shifting tool may be safely pulled at substantially greater loads thereby increasing the odds of dislodging. Thus, the occurrences of added follow-on interventional applications addressing stuck actuator arms may be reduced, resulting in tremendous time and cost savings.

Controllably releasable shifting tool

A technique facilitates actuating a variety of components in a downhole environment. The technique utilizes displacement based activation of an atmospheric actuation chamber. Activation of the atmospheric actuation chamber may be initiated via a variety of mechanisms, including manipulation of a restraining device, translation of a seal, and/or destruction of a seal. The atmospheric actuation chamber is coupled in cooperation with the corresponding downhole component to enable selective activation of the downhole component.

Downhole displacement based actuator

Implementations of various technologies are directed to a downhole actuation tool. In one implementation, the downhole actuation tool includes a tubular housing, an oil piston disposed inside the tubular housing, and a first housing disposed inside the tubular housing. The first housing includes an orifice. The downhole actuation tool may further include an oil chamber defined by the oil piston, the first housing and the tubular housing. The oil chamber includes oil. The downhole actuation tool may further include a sliding element disposed inside the tubular housing proximate the first housing.

An integrated pumping system for use in environments, such as subterranean environments, to move a desired fluid from one location to another. The integrated pumping system comprises one or more stages that each have an integrated pump and motor. A controller may be utilized to individually control the one or more integrated pumps and motors.
