US Classification:

277606, 277608, 277609, 277616, 277644

Abstract:

A seal ring for sealing between first and second members each having an outer groove surface and inner groove surface includes a metal seal body for engagement with the outer groove surface on the first and second members, and a metal flexible flange with a cantilevered end of a flexible flange providing substantially line contact sealing engagement with the inner groove surface on respective first and second member. The metal flexible flange is configured for being fluid pressure energized, and is deformed beyond its elastic limit when securing members secure the first member to the second member.

Filed:

May 5, 1988

Appl. No.:

7/190610

Inventors:

Samuel W. Putch - Houston TX

International Classification:

F16L 3500

US Classification:

285 18

Abstract:

A ratcheting and threaded connector for connecting an upper and lower tubular member which allows an upper member to be connected to a lower member with a ratcheting action and on subsequent rotation causes a threaded spring to move into position to engage shoulders on both the upper and lower members to place them in a rigid and tight relationship. Multiple load bearing shoulders on each of the members coact with load bearing shoulders on the spring to provide a substantially equal balance load distribution and allows the connector spring to have a minimum thickness.

Appl. No.:

7/400427

Inventors:

Samuel W. Putch - Houston TX

International Classification:

E21B 33043
E21B 3414

US Classification:

166348

Abstract:

A subsea well completion system having an improved tubing hanger that includes passageways through the hanger to one or more of the tubing annulus, the casing annulus and seals. The passageways may include vertically extending seal bores which are normally closed by check valves which may be operated to the open position. A tree adapter is connected to the tubing hanger and includes passageways coacting with the hanger passageways and includes externally connected side ports. The check valves may be selectively and remotely controlled externally of the completion system for monitoring the various annulus. The system may be abandoned by pumping cement through the passageways to seal them off and thereafter severing the completion system without the aid of a drilling rig.

Appl. No.:

5/913151

Inventors:

Samuel W. Putch - Houston TX

International Classification:

F16L 3500

US Classification:

285141

Abstract:

A well pipe hanger assembly for suspending an inner pipe from an outer pipe. A hanger body with an annular recess in its outer peripheral surface in which a resiliently expandable and contractible locking ring is positioned in the recess between two stop shoulders for engagement with a matching profile on the inner peripheral surface of the outer pipe. The locking ring includes first and second telescoping portions with a re-engageable releasing means betweeen the first and second portions, initially holding the portions together but allowing longitudinal disengagement and re-engagement of the telescoping portions. Preferably, the re-engagable releasing means includes beveled cam surfaces on each portion thereby providing a recockable expanding hanger which automatically allows recocking of the locking means upon upward movement of the hanger body.

Appl. No.:

5/595242

Inventors:

Samuel W. Putch - Houston TX

International Classification:

F16L 3500

US Classification:

285 18

Abstract:

A locking assembly for use in a well for locking a first member to a second tubular well member which includes a locking notch. The assembly includes a locking dog carried by the first member and a locking sleeve positioned for longitudinal movement towards and away from the back side of the locking dog for locking and releasing the dog from the notch. The first member and sleeve are telescopically positioned relative to each other for longitudinal movement with a limited longitudinal lost motion between the first member and sleeve allowing longitudinal movement therebetween for setting and releasing the lock, but preventing disengagement between the first member and the sleeve so that the first member may be retrieved by retrieving the sleeve. A seal assembly connected to the locking assembly for sealing between a wellhead and a casing hanger which is locked in place by the locking assembly and is actuated by a rotative movement with non-threaded engaging means for energizing a resilient seal thereby avoiding remotely engaging threads. The seal assembly includes a left-handed threaded connection for energizing the seal by right-handed rotation thereby avoiding left-hand rotation in the well bore.
