US Classification:

166373, 1663324, 166237

Abstract:

Embodiments of the present invention disclose apparatus and methods that can be used to mechanically actuate a downhole tool with an expandable shifting tool. One embodiment of the invention is an expandable shifting tool comprising a housing having an outer diameter and a plurality of radially extendable elements.

E21B 3410

US Classification:

166375, 166320, 166321, 166386

Abstract:

A valve assembly to control the intake of fluid. The valve assembly has a valve body and a valve choke disposed therein. The valve choke has a choke bore through the interior of the valve choke. The valve choke has a plurality of orifices to the choke bore spaced at intervals along the valve choke. A seal is disposed between the valve body and valve choke.

Appl. No.:

12/415501

Inventors:

Oguzhan Guven - Houston TX, US
Ricardo Martinez - Spring TX, US
Steven L. Anyan - Missouri City TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 34/10

US Classification:

166375, 166319, 1663342, 137861

Abstract:

A switching apparatus, system, and method configured to operate at least a dual line downhole tool via a single pressure source are provided. The switching apparatus may comprise a housing configured to contain a switching piston actuated by a fluid pressure source. The apparatus may further contain a switching valve comprising a first and second coupling passageway coupled to a switching valve housing comprising four ports. The switching piston may actuate the switching valve, alternating the coupling between a first configuration in which the four ports are communicatively coupled into two sets of ports and a second configuration in which the four ports are communicatively coupled into an alternate two sets of ports. The first configuration may configure the fluid pressure source to actuate the downhole tool in a first manner and the second configuration may configure the fluid pressure source to actuate the downhole tool in a second manner.

Inventors:

Oguzhan Guven - Houston TX, US

Ricardo Martinez - Spring TX, US
Frank Coss - Katy TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 34/06
E21B 34/00

US Classification:

166331, 166319, 166373, 166374

Abstract:

A technique enables failsafe control over actuators used to actuate downhole tools. The technique may utilize a well system having a tool with an adjustable member. An actuation mechanism serves as a fail-as-is mechanism and works in cooperation with the adjustable member. The actuation member is shiftable upon receiving a predetermined input; however the actuation member does not move the adjustable member upon each shift. Once the actuation member has been shifted the requisite number of times to move the adjustable member to another position, at least one subsequent shift of the actuation member is not able to cause movement of the adjustable member. The result is a fail-as-is technique for ensuring the tool is not inadvertently actuated to another operational position.

Assignee:

SCHLUMBERGER TECHNOLOGY CORPORATION - SUGAR LAND TX

International Classification:

E21B 34/06
E21B 34/14
B21D 51/16

US Classification:

1663323, 2989012

Abstract:

A technique employs a formation isolation valve that utilizes a ball rotatably mounted within a valve housing. The valve is designed to enable rotation of the ball about a fixed axis without translation of the ball. Rotation of the ball is achieved by connecting an arm to the ball at a position offset from the axis of rotation. A movable mandrel also is connected to the arm to enable selective actuation of the ball.

International Classification:

E21B 34/06
F17D 1/00

US Classification:

166373, 137 1, 166316

Abstract:

A technique facilitates controlling flow of fluid along a flow passage. A flow control assembly is placed along a flow passage, and a bypass is routed past the flow control assembly. Flow along the bypass is controlled by a flow bypass mechanism which may be operated via a pressure or other interventionless application. The pressure, or other interventionless application, is used to actuate the flow bypass mechanism so as to selectively allow flow through the bypass.
