Comments

The Independence Hub will produce gas from discoveries that have been made in the Eastern and Central Planning Areas by lead operator Anadarko Petroleum Company and partners that include Dominion, Kerr-McGee, Spinnaker and Murphy.  The discoveries in the Eastern Planning Area include Spiderman (DeSoto Canyon Blocks 620 and 621), San Jacinto (DeSoto Canyon Block 618), Atlas Northwest (Lloyd Ridge Block 5), Atlas (DeSoto Canyon Block 50), Mondo Northwest (Lloyd Ridge Blocks 1 and 2), and Cheyenne (Lloyd Ridge Block 399).  Discoveries in the Central Planning Area include Jubilee (Atwater Valley Blocks 305 and 349), Vortex (Atwater Valley Block 261), and Merganser (Atwater Valley 37).  The Hub topsides will be located in Mississippi Canyon Block 920, 110 miles (177 km) southeast of the Mississippi River Delta.

This will be a succession of world record water depths for completions ranging from 7,900 ft (Merganser) to 9000 ft (Atlas). The equipment is not insulated. Trees are trim FF. ManTIS equipment is trim EE.
