US Classification:

166368, 277650, 277312

Abstract:

An annular seal assembly for forming a seal between two annular surfaces. The seal assembly includes an annular base including a sealing surface. The seal assembly also includes a pair of spaced apart rims extending from the annular base opposite the base sealing surface and in opposite directions, the rims also including sealing surfaces. The base is elastically deformable and the rims are elastically deformable relative to the base to effect a self-energized seal between the two annular surfaces.

Assignee:

CAMERON INTERNATIONAL CORPORATION - Houston TX

International Classification:

E21B 33/03
E21B 33/12
F16J 15/10

US Classification:

277322, 277644, 277650

Abstract:

A seal, in certain embodiments, includes a seal body having a groove on a face of the seal body. The face is configured to contact a surface of a separate component to form a seal. The groove interrupts continuity of the face between a first face portion and a second face portion. In addition, the groove enables material deformation laterally between the first face portion and the second face portion. Furthermore, the groove increases contact stress at corners between opposite walls of the groove and the respective first and second face portions.

International Classification:

E21B 34/02
E21B 33/068
E21B 33/04

Abstract:

A system and method for accessing a well, in certain embodiments, includes a production tree, a cap, and a spool including a longitudinal bore configured to receive a tubing hanger. The tubing hanger includes a longitudinal bore configured to transfer product between the spool and the production tree. At least one adjustable fluid barrier is included in the tubing hanger and/or the cap. The adjustable fluid barrier can be used to open and close the longitudinal passage and allow access through the tubing hanger and/or the cap.
