Patent number: 7275600Abstract: Apparatus and methods of expanding tubular members are disclosed. In one embodiment, the apparatus includes a vibrating device that is capable of imparting a longitudinal and/or lateral and/or oblique vibration to a tubular member or string as it is being run into a borehole or wellbore. In another embodiment, the vibrating device imparts a longitudinal and/or lateral and/or oblique vibration to a tubular member and/or expander device, as the tubular member is being radially expanded by the expander device.Type: GrantFiled: January 16, 2003Date of Patent: October 2, 2007Assignee: E2Tech LimitedInventor: Philip Michael Burge

Patent number: 7275602Abstract: Methods and apparatus for expanding tubulars are disclosed. The tubulars may be part of a tubular string for isolating one or more zones within a wellbore. In one embodiment, the tubular string includes a first expandable zone isolation unit disposed on a first side of a zone to be isolated, a second expandable zone isolation unit disposed on a second side of the zone to be isolated, and a perforated tubular disposed in fluid communication with a producing zone. The tubular string may be expanded using an expansion assembly having a first expander for expanding the first and second expandable zone isolation units and a second expander for expanding the at least one perforated tubular. Tags or markers along the tubular string may indicate locations where expansion is desired such that connections or connectors between joints are not expanded.Type: GrantFiled: September 30, 2004Date of Patent: October 2, 2007Assignee: Weatherford/Lamb, Inc.Inventors: Annabel Green, Lev Ring, Colin McHardy, Simon Harrall, Gary Johnston, Neil A.

Patent number: 7264047Abstract: 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: GrantFiled: January 19, 2007Date of Patent: September 4, 2007Assignee: Halliburton Energy Services, Inc.Inventors: Michael M. Brezinski, Gregory B. Chitwood, Gary P. Funkhouser, Jody R. McGlothen, Thomas W. Ray, Robert S. Taylor, Bradley L. Todd
