Patent number: 7789135Abstract: 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: GrantFiled: December 23, 2009Date of Patent: September 7, 2010Assignee: 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: 6119783Abstract: A linear indexing apparatus and associated methods of using same provide convenient operation of tools in a subterranean wellbore. In a preferred embodiment, a linear indexing apparatus has an outer tubular housing and a tubular mandrel axially slidably disposed within the housing. Two sets of slips are utilized to incrementally displace the mandrel relative to the housing. A piston associated with one of the sets of slips permits the mandrel to be incrementally indexed in response to a series of repeated applications of a predetermined differential pressure.Type: GrantFiled: March 13, 1998Date of Patent: September 19, 2000Assignee: Halliburton Energy Services, Inc.Inventors: Charles D. Parker, Perry C. Shy, Rennie L. Dickson, Leo G. Collins, John C. Gano
