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.

International Classification:

E21B 23/00
E21B 17/00

US Classification:

166382, 1662421

Abstract:

A method of supporting a pressure bearing wall against a pressure differential applied across the wall can include positioning a support structure proximate the pressure bearing wall, the support structure having a support surface formed thereon, and the support surface contacting the pressure bearing wall and supporting the wall against the pressure differential. A pressure bearing housing assembly can include a pressure bearing wall and a support structure which supports the pressure bearing wall against a pressure differential applied across the wall. A well system can comprise a well tool including a pressure bearing housing assembly exposed to pressure in a wellbore, whereby a pressure differential is applied across a pressure bearing wall of the housing assembly, the pressure bearing wall being supported against the pressure differential by a support structure.

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

B01F 13/08

US Classification:

366108, 366273, 366144

Abstract:

A system for mixing a formation fluid sample obtained in a downhole sampling chamber. The system includes a mixing element disposed in the downhole sampling chamber. A support stand is operable to receive the downhole sampling chamber. A magnetic field generator is operably associated with the downhole sampling chamber such that when the magnetic field generator generates a magnetic field, the mixing element moves through the formation fluid sample responsive to the magnetic field, thereby mixing the formation fluid sample.

International Classification:

F16K 114

US Classification:

251188

Abstract:

Disclosed is an improved ball valve structure and a well safety valve utilizing the improved ball valve. The improved valve includes a metal seat member having a resilient section and control arms, which may be positioned to initially sealingly engage the seat with the ball and to compress the seat resilient section to control the force sealingly engaging the seat with the metal ball and thereby limit frictional forces opposing opening rotational forces when pushing on the seat to open the valve. The control arms are positioned by rings threaded on the seat above the control arms and below a shoulder in each arm. When the seat is moved down to open the ball valve, opening rotational forces are imparted to the valve ball through both the seat and control arms. The well safety valve utilizing the improved ball valve structure includes an annular metal valve and means increasing the force sealingly engaging the seat with the valve ball as pressure below the closed ball valve increases.
