The Stampede field is located 115 miles south of Fourchon, La.

The Stampede deepwater oil and gas field is one of the largest undeveloped fields in the Gulf of Mexico, with estimated gross recoverable reserves in the range of 300-350 million barrels of oil equivalent.

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.
When onstream, anticipated in the first quarter of 2018, Stampede 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 Chevron subsidiary, Statoil and Nexen Petroleum Offshore U.S.A., a CNOOC ltd company, each have a 25% working interest.

As of Q3 2017, all pipeline pre-commissioning was completed. Three wells have been drilled and completed, and first oil now expected to be achieved during the first quarter of 2018, which is 6 months ahead of schedule and well below budget.

Production facilities will consist of subsea production and injection wells tied back to a single Tension Leg Platform (TLP). Gross topsides processing capacity for the project is approximately 80,000 barrels of oil 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 will be drilled from two drill centers with piggable flowlines tying the wells back to the TLP. A two-rig drilling program is planned with the second rig commencing operations in 2017.

Artificial lift will be required for the field, and water injection may be utilized for reservoir pressure support. A total of 6 producers and 4 water injection wells are anticipated.
