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.

System and method for accessing a well

A system, in certain embodiments has, a fluid seal having a seal body, including a seal interface having one or more engagement portions, a first elastomer portion disposed along the seal interface, and a second elastomer portion disposed along the seal interface, wherein the first and second elastomers have material properties that are different from one another.

Multi-elastomer seal

A system, including an inner body, an outer body disposed about the inner body, and a grooved seal, wherein the grooved seal includes a sealing face and first and second side faces, wherein the first side face includes a first groove, the second side face includes a second groove, and the sealing face includes a third groove, wherein one of the inner body or the outer body includes an annular channel, and the grooved seal is disposed in the annular channel to seal an annular space between the inner body and outer body, wherein the sealing face seals against one of the inner body or the outer body, the first side face having the first groove seals against a first sidewall of the annular channel, and the second side face having the second groove seals against a second sidewall of the annular channel.

Seal having stress control groove

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.

Self-energizing annular seal

A subsea connector for connecting an upper subsea component to a lower subsea component of a drilling, production, or completion system. The subsea connector includes locking members configured to move radially inward to engage the upper and lower subsea components in a locked position, and radially outward to return to an unlocked position. The locking members are hydraulically or mechanically actuatable. The subsea connector particularly may include a locking member such as a dog or collet connector disposed in the subsea connector to lower the bending moment of the system, thereby increasing the bending capacity of the system.

Subsea connector

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.
