CNOOC Limited announced that the Hess operated Stampede Field, located in the deepwater Gulf of Mexico, commenced production. The Stampede deepwater oil and gas field is one of the largest undeveloped fields in the Gulf of Mexico.
Discovered in 2005, Stampede is located 115 miles south of Fourchon, LA., in the Gulf of Mexico (Green Canyon Blocks 468, 511 and 512). The field is located in approximately 3,500 feet of water, with a reservoir depth of 30,000 feet.
Production facilities consist of subsea production and injection wells tied back to a single Tension Leg Platform (TLP). The facility is designed for a gross topsides processing capacity of approximately 80,000 barrels of oil per day, 40 million standard cubic feet of natural gas per day, and 100,000 barrels of water injection capacity per day. The Stampede reservoir consists of several pay intervals layered within a span of 3,000 feet at that depth. The subsea production wells are being drilled from two drill centers with piggable flowlines tying the wells back to the TLP. A two-rig drilling program is underway.
Nexen Petroleum Offshore U.S.A. Inc., a wholly owned affiliate of CNOOC Limited, has a 25 percent working interest in Stampede Field. Hess Corporation, Union Oil Company of California, a subsidiary of Chevron Corporation and Statoil Gulf of Mexico LLC, each have a 25 percent working interest while Hess is the operator.
