Chevron Corp. said it has made a significant oil discovery at the Anchor prospect in the deepwater U.S. Gulf of Mexico (GoM). Anchor is Chevron’s second discovery in the deepwater GoM in less than a year.

The Green Canyon Block 807 Well No. 2 encountered oil pay in multiple Lower Tertiary Wilcox Sands. The well, which was spudded in August 2014, is located about 225 km (140 miles) off the coast of Louisiana in 1,580 m (5,183 ft) of water and was drilled to a depth of 10,287 m (33,749 ft). Appraisal drilling will begin in 2015.

Chevron subsidiary Chevron U.S.A. Inc. is the operator, with a 55% working interest in the Anchor prospect. Anchor co-owners are Cobalt International Energy, Inc. (20%), Samson Offshore Anchor, LLC (12.5%); and Venari Resources LLC (12.5%).
