Patent number: 7234547Abstract: A sponge core barrel for use in performing sponge coring and methods of assembling the sponge core barrel, as well as methods of performing sponge coring. The sponge core barrel includes an outer barrel assembly, a core bit secured to a lower end thereof, and an inner barrel assembly disposed therein. The inner barrel assembly may comprise multiple, sponge-lined inner tube sections and may also include a near-bit swivel assembly. The sponge core barrel may include a piston assembly configured to be released by contact with a core sample without imparting high compressive forces to the core. The sponge core barrel may also include a pressure compensation mechanism and, optionally, a thermal compensation mechanism cooperatively configured to maintain the pressure of presaturation fluid. The sponge core barrel may also include a valve assembly enabling the make-up and presaturation of multiple, sections of inner tube to form a single, continuous chamber.Type: GrantFiled: February 9, 2006Date of Patent: June 26, 2007Assignee: Baker Hughes IncorporatedInventors: Luc Van Puymbroeck, Bob T. Wilson, Holger Stibbe, Hallvard S. Hatloy

Patent number: 7055626Abstract: A core bit for cutting core samples in subterranean formations. The core bit has interior geometric features configured to control the quantity of drilling fluid, or flow split, flowing into a narrow annulus defined by an inside diameter of the core bit and an outside diameter of a core shoe. Reducing the flow split minimizes fluid invasion of a core being cut; thus, the core bit provides increased core quality and recoverability. The core bit is also adaptable for use with conventional core barrel assemblies and conventional coring techniques.Type: GrantFiled: March 15, 2002Date of Patent: June 6, 2006Assignee: Baker Hughes IncorporatedInventors: Michael R. Wells, Luc Van Puymbroeck, Holger Stibbe

Patent number: 6006844Abstract: A core barrel having an inner tube for coring and, alternately, a center plug assembly for closing the throat of the core bit at the bottom of the assembly for drilling in lieu of coring. The inner tube assembly and plug assembly are disposable and retrievable through the drill string on a wireline using an overshot. The core bit is of a stabilized, preferably anti-whirl, design and may be a low-invasion core bit used in cooperation with a low-invasion coring shoe. A logging tool and data transmission assembly may be incorporated in the plug assembly for logging while drilling. Alternatively, sensors for logging borehole parameters and a data transmission assembly may be incorporated in the inner tube assembly, in the wall of the core barrel, above the core barrel, or in a combination of such locations.Type: GrantFiled: October 17, 1996Date of Patent: December 28, 1999Assignee: Baker Hughes IncorporatedInventors: Luc Van Puymbroeck, John W.
