HOUSTON, Sept. 7 -- Chevron Corp. selected Mustang, a Wood Group company, for doing the detail design work on the topsides of the semisubmersible floating production unit for the deepwater Jack and St. Malo fields in the Walker Ridge area of the Gulf of Mexico.

Mustang also will provide detailed engineering for the integrated control and safety systems.

The FPU will be moored in 7,000 ft of water and will have a design processing capacity of 150,000 boe/d. The fields, discovered in 2003 and 2004, are within 25 miles of each other.

The Jack and St. Malo facility is Chevron's second production semisubmersible in the gulf.

Chevron is the operator of the development and has a 50% interest in Jack (Walker Ridge Blocks 714, 715, 758, 759, and a portion of 802 and 803) and a 51% interest in St. Malo (Walker Ridge Blocks 673, 674, 677, and 678).

The combined fields may contain more than 500 million bbl of potentially recoverable oil, according to Chevron.

The fields will produce from Lower Tertiary reservoirs that are at a 26,500 ft depth.

Chevron expects production to start in 2014.
