The Baker Hughes 95/8-in. Onyx 10E (P)erformance subsurface safety valve for big bore applications helps you maximize production rates while reducing completion costs. This surface-controlled tubing-retrievable safety valve (TRSV) is part of the Onyx series, which is based on the successful Baker Hughes T-Series valves.

The Onyx 10E valve combines a sophisticated, patented closure mechanism and premium housing threads to produce the industrys first TRSV with full-opening production in smaller casing sizes. Benefits are lower cost of a smaller, slimline outside diameter (OD) casing; flexibility in completions design; and increased production typical of larger tubing sizes.

The Onyx 10E valve also allows broader application coverage while running capillary lines for downhole instrumentation or chemical injection, and cables for electric submersible pump operation. Dual completions can also be installed.

Offering maximum value combined with unsurpassed reliability, Baker Hughes introduced the industrys first 7-in. (177.8-mm) TRSV that can fit inside a 95/8-in. (244.4-mm) casing with cable bypass capabilities. Additionally, Baker Hughes introduced the industrys first 4-in. (114.3-mm) TRSV to fit inside a 7-in. (177.8-mm) casing. The Onyx 10E valve incorporates a nonelastomeric dynamic seal assembly for pressure and temperature exceeding 28,000 psi (1,930.5 bar) and 450F (232C), ensuring reliable strength and sealing capabilities in the most extreme conditions.
