Project Profile
Value: Undisclosed
Location: Canyon Block 243 Gulf of Mexico, 170km south-east New Orleans, USA
Start-up Year: November 2003
Peak Production: 33,000 barrels of oil equivalent per day
Water depth: 850m
The Matterhorn field is located in Mississippi Canyon Block 243 in the deepwater Gulf of Mexico, approximately 170km south-east of New Orleans, US. The field, which lies in 850m of water, came onstream in November 2003 and has a production capacity of 33,000 barrels of oil equivalent per day. The Matterhorn field was wholly owned and operated by TotalFinaElf E&P USA. In April 2010, Total sold its 100% interest in the field to W&T Offshore. The Matterhorn field was discovered in 1999 with the drilling of the Matterhorn discovery well. The well was drilled by Global Marine Celtic Sea semi-submersible to a depth of 8,165ft. The well encountered 370ft of oil.
The contract for the hull was won by Keppel Fels in Singapore, making Matterhorn also the first one built outside of the Gulf of Mexico. Paragon Engineering was responsible for the design of the topside facilities, employing the 3D Plant Design Management System (PDMS). The company expended over 60,000 man-hours on the design. The steel tubular tendons to connect the TLP were fabricated by Kiewit Offshore Service. The 415t piles for the tendons were fabricated by Gulf Marine Fabricators.
