Publication number: 20070267201Abstract: The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.Type: ApplicationFiled: August 3, 2007Publication date: November 22, 2007Applicant: HALLIBURTON ENERGY SERVICES, INC.Inventors: Michael Brezinski, Gregory Chitwood, Ralph Echols, Gary Funkhouser, John Gano, William Henderson, Paul Herman, Marion Kilgore, Jody McGlothen, Ronald Powell, Alex Procyk, Thomas Ray, Michael Sanders, Roger Schultz, David Steele, Robert Taylor, Bradley Todd, Cynthia Tuckness

Publication number: 20050269074Abstract: An oilfield tool comprising a body of high chromium, low carbon steel and a high hardness surface having a supersaturated level of carbon. The body may be manufactured from a Super 13Cr type stainless steel. The tool may be carburized to a supersaturated level providing a surface hardness of about 55 HRC to 62 HRC and have an effective case depth of at least 0.020 inch at which depth the hardness is 50 HRC. The tool body is heat treated to a body hardness of about 39 HRC. A surface of the tool may be surface coated, e.g. nitrided or borided. The tool may be an expansion cone and may be a variable diameter expansion cone.Type: ApplicationFiled: June 2, 2004Publication date: December 8, 2005Inventor: Gregory Chitwood
