Tech Report: TRC-II Tubing-Retrievable Charged Safety Valve Successfully Set in GOM at Record Depth of 13,248 ft

Safety valve in Gulf of Mexico well provides operating redundancy, well integrity, and long-term reliability at a depth previously unattainable

TRC-II tubing-retrievable charged safety valve set in GOM at record depth.

An ultradeepwater well in the Gulf of Mexico, drilled to 17,715 ft [5,400 m], encountered 56 net feet of natural gas pay in Upper Miocene reservoirs. The well was capable of producing 5,000 bbl/d of condensate and 1 Bcf/d of gas. The operator needed a reliable safety valve that would help preserve well integrity in the event of emergency at a depth greater than 13,000 ft [3,962 m], a record setting depth for safety valves.

A 4½-in TRC-II tubing-retrievable charged safety valve provided the solution. The 13,248-ft setting depth of the TRC-II safety valve is more than 12 times the height of the Eiffel Tower in Paris and almost 5 times the height of the world’s tallest building, the Burj Khalifa, in Dubai.
