Patent number: 8387744Abstract: A marine seismic source comprises a housing having a central axis, an open end, and a closed end opposite the open end. In addition, the seismic source includes a piston extending coaxially through the open end of the housing. The piston is adapted to axially reciprocate relative to the housing. Further, the piston has a first end distal the housing and a second end disposed within the housing.Type: GrantFiled: December 29, 2010Date of Patent: March 5, 2013Inventors: Mark Harper, Joseph A. Dellinger, Martin Thompson, Graham Openshaw

Publication number: 20120275274Abstract: Sensor and communications systems for communicating measurements from subsea equipment, such as at an offshore well, to the surface. A sensor for a physical parameter, such as pressure or temperature at a blowout preventer, capping stack, or conduit in communication with the same, is electrically connected to a subsea acoustic transponder. An acoustic monitoring transponder deployed near the well periodically interrogates the acoustic transponder with an acoustic signal, in response to which the acoustic transponder transmits an acoustic signal encoded with the measurement. The measurement data are stored at the acoustic monitoring transponder. An acoustic communications device later interrogates the acoustic monitoring transponder to receive the stored measurement data for communication to a redundant network at the surface.Type: ApplicationFiled: April 20, 2012Publication date: November 1, 2012Applicant: BP CORPORATION NORTH AMERICA INC.Inventors: Matthew Gochnour, Graham Openshaw, Jonathan Peter Davis

Patent number: 6975560Abstract: A method and apparatus is disclosed for performing a seismic survey below the surface of a body of water and on the seabed. In one embodiment, a plurality of seismic data receivers are removably loaded in a carrier located above the surface of the water and the carrier is lowered into the water and placed at a depth relatively close to the seabed. Each of the receivers has a memory for recording the vibrations of the seabed and has a switch for activating the memory. A ROV is used to unload the receivers from the carrier and to deposit each receiver on the seabed and along a survey line. In one embodiment, the receivers comprise a frame, a pressure vessel for housing the memory and remotely activated controls, and a geophone that is separately planted into the seabed at a relatively short distance from the frame.Type: GrantFiled: March 25, 2003Date of Patent: December 13, 2005Assignee: BP Corporation North America Inc.Inventors: Eivind W. Berg, Scott T. Michell, Nigel P. Purnell, Graham Openshaw, Atle H. Fyhn, Gerard J. Beaudoin
