Filed:

Feb 6, 2013

Appl. No.:

13/760149

Inventors:

Andrew John Webber - Coppell TX, US

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 34/06

US Classification:

1663323, 1663342, 251208

Abstract:

A wellbore ball valve includes a ball-type valve closure having an interior, central bore. A lower ball carrying assembly defines a first annular, sealing seat surface in contact with and adapted to seal with the exterior of the valve closure. The first seat surface defines a first through hole. An upper assembly defines a second annular seat surface in contact with the exterior of the valve closure. The second seat surface defines a second through hole. The second through hole is shaped differently from the first through hole in that it at least partially overlaps with the central bore while the first through hole is sealed from the central bore.

US Classification:

166386, 166373, 1663323, 1663342

Abstract:

A ball valve comprises a housing, a first seat surface, a second seat surface, and a ball rotatably movable within the housing. The ball contacts at least one of the first seat surface and the second seat surface to form a seal within the ball valve. The first seat surface and the second seat surface are fixed relative to each other, and pressure acting in a first direction and in a second direction opposite the first direction increases the contact pressure of the first seat surface and the second seat surface with the ball.

Assignee:

HALLIBURTON ENERGY SERVICES, INC. - Houston TX

International Classification:

E21B 34/06
E21B 23/00

US Classification:

166386, 166113, 166381

Abstract:

A well tool with a housing has an actuator sleeve in the housing. The actuator sleeve has an internal shifting tool engaging profile. An actuator is in the housing. The actuator is responsive to a remote signal to move the actuator sleeve from a first position to a second position. A dog is in the housing, supported to couple the actuator sleeve to the actuator when the actuator sleeve is in the first position and unsupported to allow the actuator sleeve to uncouple from the actuator when the actuator sleeve is in the second position.

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 34/06
F16K 5/06

Abstract:

A composite wellbore ball valve has a spherical, fiber reinforced composite ball valve closure. The closure has an interior, central through-bore and an annular metallic sealing surface. A ball carrying assembly has an annular, metallic sealing seat surface adapted to contact and form a metal-to-metal seal with the metallic sealing surface of the ball valve closure when the ball valve closure is closed.
