Abstract

999,838. Wells. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. June 25, 1963 [June 27, 1962], No. 25298/63. Heading E1F. A valve 40 is interposed in a conduit 34 between a readily disconnectible joint 51 and an underwater wellhead 33 from which the conduit extends. The conduit which may be used for the return of drilling fluid to the working platform at the surface or for cement circulation has a further valve 41 and a dump valve 42 both operated remotely from this platform. The joint is also operated from the platform and is arranged so that when its parts 52, 54 are separated the normally open valve 40 closes. The joint may be replaced by telescoping sleeves shear pinned together.
