Appl. No.:

11/307768

Inventors:

Arin Basmajian - Houston TX, US
Grigory L. Arauz - Missouri City TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 34/00

US Classification:

166319, 166321, 166383, 166387

Abstract:

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.

International Classification:

E21B 34/14

US Classification:

166373, 166321, 1663341, 166123, 166181, 166 72

Abstract:

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.

International Classification:

E21B 23/00
E21B 43/00

US Classification:

166381, 166113

Abstract:

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.
