HIGH-PRESSURE COILED TUBING INSTRUMENTAL IN DEEPWATER WELL WORK

摘要

The Troika field is located in the U.S. Gulf of Mexico in 2,700 ft of water. Troika wells are high-rate, high-pressure wells capable of flowing more than 30,000 BOPD and 60 MMscf/D gas. Shut-in tubing pressure is 6,000 psi with produced fluids in the well-bore. Coiled-tubing (CT) operations were performed from a semisubmersible in rough seas with waves as high as 9 ft.
