For successful deepwater completions-select, displace, filter

摘要

TODAY'S CHALLENGING Gulf of Mexico deepwater completions require new technologies to protect reservoirs and maximize their productivity. Key considerations include: 1.Precise selection of the appropriate completion fluid: compatible with associated fluids, sufficiently dense at the seafloor-and fully capable of inhibiting gas hydrates, which form readily at the high pressures and low temperatures at the BOP/wellhead of deep subsea wells. Gas hydrates plug choke and kill lines, BOPs, risers and flowlines in a kick. They also interfere with drillstring movement and BOP operation-and can liberate large quantities of gas near the surface as they decompose or melt.
