Publication number: 20120208934Abstract: Through the combination of at least two polymer families, and the optimization of other components, a rubber compound has been developed for use in downhole applications that will swell in water-based fluids. A cellulose component, such as carboxy methyl cellulose (CMC), is used together with an acrylate copolymer (AC) that can increase the swelling capacity of an acrylonitrile butadiene rubber (NBR) in water. The amount of swelling achieved depends on physical boundaries and limitations, the salinity of the water, and the temperature.Type: ApplicationFiled: April 24, 2012Publication date: August 16, 2012Applicant: Baker Hughes IncorporatedInventors: James R. Korte, John J. Thurston, James Edward Goodson

Patent number: 8118092Abstract: A swelling packer is covered with a material that is preferably in a tubular form and slipped over the swelling element to be shrink fit with applied heat. The material is formulated to break down at temperatures slightly below the expected downhole temperatures so that ideally the packer has about 48 hours of swelling delay which is normally a time period long enough to allow it to be properly located without it swelling so much as to cause it to be damaged by running in. Various polymers can be used to make an imperious covering for run in that on the way starts to break down. Ideally the material for the cover disappears about the time of sealing or shortly thereafter.Type: GrantFiled: September 16, 2009Date of Patent: February 21, 2012Assignee: Baker Hughes IncorporatedInventors: James R. Korte, Kent A. Evans, Dustin D. Ellis, John J. Thurston, Anthony P. Foster, Steve Rosenblatt

Publication number: 20090178800Abstract: A packer for downhole use responds to water containing fluids by swelling from its core. The core is preferably covered with an outer layer that preferably has a lower rate of diffusion and swelling than the core that it surrounds. Because of this arrangement, the packer can be delivered to the desired location before it is set by swelling of the core. The outer layer can also be responsive to water containing fluids by dissolving slowly to allow time to properly position the packer before the core swells to a sealing relationship with the surrounding tubular or the wellbore wall.Type: ApplicationFiled: January 14, 2008Publication date: July 16, 2009Inventors: James R. Korte, Edward T. Wood

A cellulose component, such as carboxy methyl cellulose (CMC), is used together with an acrylate copolymer (AC) that can increase the swelling capacity of an acrylonitrile butadiene rubber (NBR) in water to over 1000%. The amount of swelling achieved depends on physical boundaries and limitations, the salinity of the water, and the temperature.Type: ApplicationFiled: September 30, 2008Publication date: April 2, 2009Applicant: Baker Hughes IncorporatedInventors: James R.

Patent number: 7441596Abstract: A sealing element that swells on exposure to well fluids present or added to the wellbore is assembled to the mandrel in a manner to induce circumferential stresses proximately to the inside diameter of the element so as to resist the tendency of the inside diameter of the element to grow during the swelling process. A vacuum and a pressure method are described. Leak paths between the mandrel and the sealing element are minimized or eliminated as a result.Type: GrantFiled: June 23, 2006Date of Patent: October 28, 2008Assignee: Baker Hughes IncorporatedInventors: Edward T.
