Publication number: 20110135390Abstract: A system and method in which a buoyant central docking station captures, lifts and couples one or more other sea vessels is disclosed, wherein a flexible, modularized production system is quickly realized on a cost effective basis. The capabilities of a number of older, less expensive, readily available vessels are combined to achieve an effective FPSO substitute that allows lower producing fields to be explored and produced in a profitable manner. The time horizon between initiation and consummation of field operations is reduced, and older vessels that might otherwise be scrapped or retired are again made useful and seaworthy in a safe and profitable exploration and production environment.Type: ApplicationFiled: January 28, 2011Publication date: June 9, 2011Applicant: ANADARKO PETROLEUM CORPORATIONInventors: Keith K.

Patent number: 7458425Abstract: A system and method of establishing an offshore exploration and production system is disclosed, in which a well casing is disposed in communication with an adjustable buoyancy chamber and a well hole bored into the floor of a body of water. A lower connecting member joins the well casing and the chamber, and an upper connecting member joins, the adjustable buoyancy chamber and a well terminal member. The chamber's adjustable buoyancy enables an operator to vary the height or depth of the well terminal member, and to vary the vertical tension imparted to drilling and production strings throughout exploration and production operations. Also disclosed is a system and method of adjusting the height or depth of a wellhead while associated vertical and lateral forces remain approximately constant. A variety of well isolation members, lateral stabilizers and anchoring means, as well as several methods of practicing the invention, are also disclosed.Type: GrantFiled: November 22, 2004Date of Patent: December 2, 2008Assignee: Anadarko Petroleum CorporationInventors: Keith K.
