Publication number: 20100084127Abstract: A non-metallic element system is provided as part of a downhole tool that can effectively seal or pack-off an annulus under elevated temperatures. The element system can also resist high differential pressures without sacrificing performance or suffering mechanical degradation, and is considerably faster to drill-up than a conventional element system. In one aspect, the composite material comprises an epoxy blend reinforced with glass fibers stacked layer upon layer at about 30 to about 70 degrees. In another aspect, a mandrel is formed of a non-metallic polymeric composite material. A downhole tool, such as a bridge plug, frac-plug, or packer, is also provided. The tool comprises a support ring having one or more wedges, an expansion ring, and a sealing member positioned with the expansion ring.Type: ApplicationFiled: December 23, 2009Publication date: April 8, 2010Applicant: Weatherford/Lamb, Inc.Inventors: Rocky A. Turley, Craig Fishbeck, Rami Al Oudat, Patrick J. Zimmerman, Charles D. Parker, Michael R. Niklasch, William J. Eldridge, Roland Freihet, William F. Hines, III, Bill Murray

Patent number: 7690436Abstract: A wellbore pressure isolation apparatus is deployed in a wellbore and has a sealing element that can be activated to seal against an interior surface of a surrounding tubular. Once set, a ball valve in the apparatus restricts upward fluid communication through the apparatus, and another ball valve in the apparatus can restrict downward fluid communication through the apparatus. These ball valve can have disintegratable balls intended to disintegrate in wellbore conditions after different periods of time. To facilitate deployment of the apparatus in a horizontal section of the well bore, the apparatus has a plurality of rollers positioned on a distal end. In addition, the apparatus has a ring disposed about the body between the distal body portion and an adjacent body portion. The ring has an outside diameter at least greater than that of the adjacent body portion to facilitate pumping of the apparatus in the wellbore.Type: GrantFiled: May 1, 2007Date of Patent: April 6, 2010Assignee: Weatherford/Lamb Inc.Inventors: Rocky Turley, John McKeanchnie

Patent number: 7434627Abstract: A system for facilitating the insertion of a tool into a wellbore, especially a non-vertical wellbore. In one embodiment a tool is fixable in a wellbore and includes centralizing, friction-reducing members that serve to keep the body of the tool off the walls of the wellbore. In another embodiment the tool includes a wiper ring that partially fills an annular area formed between the centered tool and the wellbore walls. The surface of the ring facing the upper end of the wellbore provides fluid resisting piston surface and permits the centered tool to be pumped down the wellbore more effectively.Type: GrantFiled: June 14, 2005Date of Patent: October 14, 2008Assignee: Weatherford/Lamb, Inc.Inventors: Rocky A. Turley, John W. McKeachnie

Publication number: 20080128133Abstract: Embodiments of the present invention generally relate to an adapter kit for use between a setting tool and a wellbore plug. In one embodiment, a method for setting a plug in a cased wellbore is provided. The method includes deploying a tool string in the wellbore using a run-in string, the tool string comprising: a setting tool coupled to the run-in string, an adapter kit, comprising an adapter sleeve, and a plug comprising a sealing member. The method further includes actuating the setting tool, wherein the setting tool exerts a force on the adapter sleeve which transfers the force to the plug, thereby expanding the sealing member into engagement with an inner surface of the casing. The method further includes separating the setting tool from the plug, wherein the adapter sleeve remains with the plug.Type: ApplicationFiled: December 5, 2006Publication date: June 5, 2008Inventors: Rocky A.
