Real-world testing abates subsea risk

摘要

Testing subsea actuators with live condensate fluids from actual field developments may become a new industry standard. Performing multiple completions on high-pressure/high-temperature (HP/HT) gas wells can be an expensive endeavor. The necessity of tripping the riser after each completion to inspect the subsea safety head increases cost - in some cases as much as USD1 million per well. StatoilHydro sought out National Oilwell Varco's (NOV) wholly owned subsidiary, Texas Oil Tools (TOT), in an effort to develop a "real-world" test.
