US Patent:

20030127224, Jul 10, 2003

Filed:

Jan 8, 2002

Appl. No.:

10/041278

Inventors:

James Vick - Dallas TX, US
Robert Guyden - Parker TX, US

International Classification:

E21B033/13

US Classification:

166/285000, 166/386000, 166/135000, 166/192000

Abstract:

A plug is provided for use in well plugging applications. In a described embodiment, the plug has a metal to metal seal on a hollow spherical structure. A change in contact pressure between the seal and a bore due to a change in differential pressure across the plug is regulated by changing characteristics of the plug structure.

Appl. No.:

10/078839

Inventors:

James Vick - Dallas TX, US

International Classification:

E21B034/10
E21B034/14

US Classification:

166/375000, 166/386000, 166/332800

Abstract:

Apparatus and methods are provided for actuation of downhole tools. In one example, a deep set safety valve uses a magnetic coupling which permits a portion of the safety valve at control line pressure to be isolated from tubing string internal pressure, without requiring the use of a dynamic seal therebetween. A piston of the safety valve may be displaced in response to a differential between control line pressure and pressure in an annulus surrounding the tubing string, pressure in another control line, or pressure in the tubing string. Other types of well tools may benefit from actuation using principles of the invention.

James Vick - Dallas TX, US
Leo Collins - Farmers Branch TX, US

International Classification:

E21B034/12

US Classification:

166332800, 166332100

Abstract:

A safety valve having an extension spring closure mechanism. In a described embodiment, a valve for use in a subterranean well is provided which includes a biasing device and a closure member having open and closed positions. The biasing device has a length which decreases as the closure member displaces toward the closed position. The biasing device may be an extension spring.

International Classification:

E21B001/00

US Classification:

166066500, 166066700, 166332800

Abstract:

Apparatus and methods are provided for actuation of downhole tools. In one example, a deep set safety valve uses a magnetic coupling which permits a portion of the safety valve at control line pressure to be isolated from tubing string internal pressure, without requiring the use of a dynamic seal therebetween. A piston of the safety valve may be displaced in response to a differential between control line pressure and pressure in an annulus surrounding the tubing string, pressure in another control line, or pressure in the tubing string. Other types of well tools may benefit from actuation using principles of the invention.

Appl. No.:

11/004471

Inventors:

Jimmie Williamson - Carrollton TX, US
James Vick - Dallas TX, US
Abram Galindo - Dallas TX, US

International Classification:

E21B 34/10

US Classification:

166321000

Abstract:

A safety valve with extension springs. In a described embodiment, a valve for use in a subterranean well includes a closure member having open and closed positions. A structure displaces to cause the closure member to displace between the open and closed positions. A biasing device has a length which decreases as the structure displaces to cause the closure member to displace toward the closed position.

Appl. No.:

11/041393

Inventors:

James Vick - Dallas TX, US
Michael Vinzant - Carrollton TX, US
James Williams - Grand Prairie TX, US

International Classification:

E21B 33/12
E21B 34/00

US Classification:

166386000, 166332800

Abstract:

A valve system for use in a subterranean well, the valve having multiple closure devices, or a closure device and a device for protecting the closure device. A valve system includes a valve with a closure assembly. The closure assembly has a closure device and a protective device which alters fluid flow through a flow passage of the valve prior to closure of the closure device to thereby protect the closure device. A safety valve system includes a safety valve with a closure assembly having at least two closure devices arranged in series for controlling flow through a flow passage of the safety valve. Another safety valve system includes a safety valve assembly including multiple safety valves arranged in parallel. One portion of fluid from a fluid source flows through one of the safety valves, while another portion of fluid from the fluid source flows through another safety valve.
