International Classification:

E21B 33/12
E21B 23/00

US Classification:

166387, 166382, 166212

Abstract:

A downhole tool for providing a seal downhole within a wellbore for reducing loading experienced by a sealing member of the downhole tool is disclosed. The downhole tool may include a pair of directional locking members, at least one of which is operable to transfer a loading experienced by the downhole tool through rigid components of the downhole tool, thereby bypassing the sealing member.

US Classification:

166382, 166383, 1662427

Abstract:

A tubular locking system comprises a first wellbore tubular, an internal locking feature disposed on an inner surface of the first wellbore tubular, a second wellbore tubular, where at least a portion of the second wellbore tubular is disposed within the first wellbore tubular, a compression sleeve coupled to the second wellbore tubular, a collet coupled to the second wellbore tubular below the compression sleeve, and a shifting sleeve disposed within the collet.

US Patent:

Filed:

May 18, 1981

Appl. No.:

6/264993

Inventors:

Gary D. Ellis - Richardson TX

Assignee:

Dresser Industries, Inc. - Dallas TX

International Classification:

E21B 33128
E21B 33129

US Classification:

166212

Abstract:

A hanger and stinger assembly includes an expandable joint therebetween for the stinger to be telescoped with the hanger between extended and collapsed positions. An actuating spool for use in conjunction with a wireline tool mechanism is provided for hydraulically actuating the slips on the hanger and a releasable catch is connected between the stinger and a tubular receptacle mounted on the hanger to normally limit upward movement of the stinger to its extended position. A latch at the upper end of the stinger is utilized to hold the catch in a release position enabling the stinger to be withdrawn from the receptacle by a straight pull and a locking mechanism normally positions the latch to keep from holding the catch in its release position and the locking mechanism is hydraulically actuated.

US Patent:

43725279, Feb 8, 1983

Filed:

May 5, 1980

Appl. No.:

6/146576

Inventors:

Irwin Rosenhauch - Rockwell TX
Gary D. Ellis - Richardson TX

Assignee:

Dresser Industries, Inc. - Dallas TX

International Classification:

E21B 3306

US Classification:

251 1A

Abstract:

A blowout preventer comprises a housing with a pair of opposed rams carrying sealing blocks for sealing against tubing extending through the housing. Openings in the front side of the housing provide access to the sealing blocks for changing the blocks and a door closes the openings during normal in-service use of the preventer. A door guide permits the door to be slid in either of two opposing edgewise directions for exposing the openings one at a time but keeps the door from being movable substantially in a broadwise direction. Sealing inserts disposed within the openings between the door and the sealing blocks serve to seal against leakage and a rack and pinion mechanism provides the means for sliding the door from a centered position closing both openings to opposite edgewise positions exposing one or the other of the openings.
