Abstract: A seal includes a seal body formed as a closed loop. The seal body having an upper surface and a lower surface. The seal body comprises an inner wall and an outer wall. The lower surface comprises an inner wing and an outer wing extending laterally from the outer surface to provide lateral sealing. The upper surface of the seal is configured to provide a sealing contact when the seal is urged into engagement via a fluid pressure.

Abstract: A blowout preventer includes a main body having a through bore and defining a passage transverse to the through bore. A seal is disposed in the main body and arranged to restrict fluid flow from the through bore to the passage. The seal comprises a seal body formed as a closed loop having an upper surface and a lower surface, wherein the seal body comprises an inner wall and an outer wall. The lower surface comprises at least one wing extending laterally from the outer surface to provide a lateral sealing surface. The upper surface comprises at least one raised portion to provide a sealing surface.

Abstract: Releasable tubular couplings entailing spring-based designs providing a mechanical solution for linking/coupling tubulars. A method for forming a releasable coupling between a first tubular member and a second tubular member.

Abstract: A blowout preventer includes a main body having a through bore and defining a passage transverse to the through bore. At least one seal is configured for positioning with an opening on the seal coincident with the through bore. The at least one seal being disposed to engage an element disposed in the transverse passage. The at least one seal being configured to receive a fluid under pressure to energize the seal to restrict fluid flow between the through bore and the transverse passage when the element is disposed proximate the through bore. A method for operating a blowout preventer.

Abstract: A blowout preventer includes a main body having a through bore. A pressure chamber is located adjacent to and transverse to the through bore. A gate is disposed in the pressure chamber. An insert is disposed in the main body and defines an opening therethrough parallel to the through bore. The insert also defines a passage therethrough transverse to the through bore for passage of the gate.
