Appl. No.:

12/353664

Inventors:

Adam D. Wright - McKinney TX, US

Kevin D. Fink - Frisco TX, US
Donald Perkins - Allen TX, US
Jimmie R. Williamson - Carrollton TX, US
Mark D. Kalman - Carrollton TX, US

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 34/06
E21B 34/00

US Classification:

166 666, 166316, 166330

Abstract:

Well tools including valves operable by low electrical input. One well tool includes a valve which controls fluid communication between pressure regions in a well, the valve including a rotatable member which is biased to rotate, and a brake or clutch which prevents rotation of the member. Another valve includes a barrier which separates reactants, with the valve being operable in response to the barrier being opened and the reactants thereby reacting with each other. Yet another valve includes a barrier which separates the pressure regions, and a control circuit which heats the barrier to a weakened state. Another valve includes a member displaceable between open and closed positions, a restraining device which resists displacement of the member, and a control device which degrades or deactivates the restraining device and thereby permits the member to displace between its open and closed positions, in response to receipt of a predetermined signal.

International Classification:

E21B 34/06
E21B 23/04

US Classification:

166317, 166376

Abstract:

A downhole actuator apparatus that selectively maintains a pressure differential between two pressure regions in a well. The apparatus includes a body defining first and second chambers. A piston is slidably disposed in the body and is selectively moveable between first and second positions. A barrier is disposed in the body to selectively separate the first and second chambers. A fluid is disposed in the first chamber between the barrier and the piston. A control system that is at least partially disposed within the body is operable to generate an output signal responsive to receipt of a predetermined input signal. The output signal is operable to create a failure of the barrier such that at least a portion of the fluid flows from the first chamber to the second chamber and the piston moves from the first position to the second position.
