Modec has confirmed it was awarded a contract by Hess to provide engineering and management services for the Stampede tension leg platform in the deep-water Gulf of Mexico in USA. Modec was set to be awarded the engineering and construction management contract. The award will see the Japanese company provide project management, engineering, procurement management, and construction management for the hull and mooring systems of a conventional TLP, with continuing services contingent upon project sanction which is expected in 2014.
This Stampede TLP development will see the joining of the Pony and Knotty Head discoveries and will be situated roughly 170 miles south-east of New Orleans in the Green Canyon Block 468 in a water depth of 3350 feet. Knotty Head is located in GC512 and was discovered in 2005 by the Knotty Head-1 discovery well. The Knotty Head 1 was drilled by the TransOcean Discoverer Spirit drillship. The well reached a total depth of 34,189ft and is the deepest well drilled in the Gulf of Mexico. The well also set a third record for the longest 14¾in-bit run at 11,545ft and a total depth of 24,085ft. The field lies in 3,500ft of water close to the Chevron-operated Tahiti and Tonga discoveries. Gross recoverable reserves have been estimated between 200 and 500 MMboe. Pony is located in block GC468 and was discovered in 2006. The fields lie in more that 3,000 feet of water.
Hess will operate the Stampede development in partnership with Chevron, Statoil and Nexen, with each company holding a 25% working interest.
In terms of the pipeline, Enbridge is working with its upstream partners at Hess Corp. to oversee pipeline developments from the oil field. Enbridge will build, own and operate a crude oil pipeline in the Gulf of Mexico to connect the planned Stampede development. The US$130 million project will start in the deepwater Stampede project and terminate 16 miles away with a connection to a third-party pipeline system. Hess Corp. launched development plans for its deepwater Stampede project in the Gulf of Mexico in late October.
Approximately 16 miles in length and 18 inches in diameter, the Stampede lateral will originate in Green Canyon Block 468, located approximately 220 miles southwest of New Orleans, Louisiana. Water depth at the location of the planned pipeline is approximately 3,500 feet. The company expects to pull at most 80,000 barrels of oil per day from the project. Total estimated recoverable reserves for Stampede are estimated at between 300 million and 350 million barrels of oil equivalent. Hess plans to drill as many as six production wells in the Stampede area starting in early 2015. First production from the field, as well as pipeline operations from Enbridge, is expected by 2018.
