U.S., Gulf of Mexico Blocks GB 200, 215 and 216

Landmark: One of FMC Technologies’ first horizontal trees completed in the Gulf of Mexico

This deepwater Gulf of Mexico project features two subsea horizontal trees located at a water depth of 1,440 ft (440 m). Producing at high pressure, the subsea trees are rated at 10,000 psi and 2500F (120C). The first well, No. 4, is located 4 miles (6 km) from Amerada Hess’s GB 260 platform. The second well, No. 2, is offset from well No. 4 an additional 0.7 miles (1.1 km). A bottom-towed flowline bundle provides tieback to the Baldpate compliant tower via a bundled SCR.

The horizontal subsea completion systems feature diverless installation and intervention, 20-year design life. Trim-Clad® seat pockets, an insert retrievable choke, tree PT sensors, two SCSSV lines, two downhole chemical injection lines and one tree chemical injection line.
