Abstract: A holding member provides for releasably positioning a rotating control head assembly in a subsea housing. The holding member engages an internal formation in the subsea housing to resist movement of the rotating control head assembly relative to the subsea housing. The rotating control head assembly is sealed with the subsea housing when the holding member engages the internal formation. An extendible portion of the holding member assembly extrudes an elastomer between an upper portion and a lower portion of the internal housing to seal the rotating control head assembly with the subsea housing. Pressure relief mechanisms release excess pressure in the subsea housing and a pressure compensation mechanism pressurize bearings in the bearing assembly at a predetermined pressure.

Abstract: The present invention generally provides a downhole tool with an improved means of transmitting data to and from the tool through the use of wired pipe capable of transmitting a signal and/or power between the surface of the well and any components in a drill string. In one aspect, a downhole tool includes a body, and a mandrel disposed in the body and movable in relation to the body. A conducive wire runs the length of the body and permits signals and/or power to be transmitted though the body as the tool changes its length.

Abstract: Den foreliggende oppfinnelse tilveiebringer generelt et nedihullsverktøy med et forbedret middel for overføring av data til og fra et verktøy ved bruk av rør med ledning som er i stand til å overføre et signal og/eller kraft mellom brønnens overflate og en hvilken som helst komponent i en borestreng. Ved ett aspekt innbefatter et nedihullsverktøy et legeme og en spindel (110) som er plassert i legemet, og hvor spindelen er bevegelige med hensyn til legemet. En ledningsforbindelse (135) løper over hele lengden av legemet og tillater signaler og/eller kraft i å overføres gjennom legemet mens verktøyet skifter lengde.
