April 19th, 2010
Abstract:
Halliburton Energy Services, Inc. (Houston, TX) earned U.S. Patent 7,696,275 for downhole nanocomposite seal elements manufactured with carbon nanotubes, carbon nanofibers and other nanomaterials. The nanocomposite seal elements include O-ring seals, D-seals, T-seals, V-seals, X-seals, flat seals, lip seals, back-up rings, bonded seals and packing elements designed to resist damage from explosive decompression during oil and gas production.
According to inventors Jeremy Buc Slay and Thomas Wayne Ray, the nanostructures and the polymer host material form interfacial interactions that improve the useful life of the seal element by minimizing seal failures associated with explosive decompression, extrusion, spiral failure, abrasion, temperature degradation and the like. Halliburton's nanocomposite seals may be used for both land based and offshore oil and gas platforms.
