Chevron Corporation announced today the successful completion of an appraisal well at its Big Foot prospect in the deepwater Gulf of Mexico. Big Foot is located in over 5,000 feet of water on Walker Ridge 29, approximately 225 miles south of New Orleans, and 180 miles offshore. The appraisal well, Big Foot no. 3, Sidetrack no. 2, confirmed the same pay intervals of the previously announced discovery and sidetrack wells, and found the main pay sand full of oil to the base.

Operated by a Chevron subsidiary, the appraisal well reached a measured depth of 25,113 feet (including water) at a location to the northwest of, and deeper than, the previous wells. Chevron is evaluating a range of production development options for the Big Foot prospect.

Chevron owns a 60 percent working interest in Big Foot. Partners are StatoilHydro (27.5%) and Shell Gulf of Mexico Inc. (12.5 %).
