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.
The project leverages Hess' proven capability to safely execute deepwater development projects.
Stampede achieved first oil in January 2018, and is expected to provide a significant contribution to Hess’ future growth.
The project was sanctioned in October 2014. Hess has a 25% working interest and is operator. Union Oil Company of California, a subsidiary of Chevron Corp., Statoil Gulf of Mexico LLC and Nexen Petroleum Offshore U.S.A. Inc., a wholly owned affiliate of CNOOC Limited company. Each have a 25% working interest.
As of Q1 2018, three wells have been drilled and completed. First oil was achieved in January 2018, and production is expected to ramp up over the next 18 months.
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 structure lies at a depth of about 30,000 feet with 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.
A total of 6 producers and 4 water injection wells are anticipated.
