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: 6788066Abstract: A highly accurate, fully compensated, high spatial resolution, wave propagation system for measuring dielectric constant and resistivity of fluids or solids in a cylindrical enclosure and method for measuring well core characteristics in-situ or in a laboratory. One embodiment of the invention relies on waves propagated from transmitters above and below two spaced receivers which transmit and receive electromagnetic waves via slots on the inner periphery of a cylinder structure. The data is then processed with a CPU either down hole for later retrieval or on the surface for real-time monitoring.Type: GrantFiled: January 16, 2001Date of Patent: September 7, 2004Assignee: Baker Hughes IncorporatedInventors: Macmillan M. Wisler, Larry W. Thompson, LucVan Puymbroeck, Holger Stibbe, Hallvard S. Hatloy
