Chevron Corporation (NYSE: CVX) announced a significant oil discovery at the Anchor prospect in the deepwater U.S. Gulf of Mexico. Anchor is the second discovery in the deepwater Gulf for San Ramon-based Chevron in less than a year.

“The Anchor discovery, along with the previously announced Guadalupe discovery, are significant finds for us in the deepwater Gulf of Mexico,” said Jay Johnson, senior vice president, Upstream, Chevron Corporation.

“We had one of our best years with the drill bit in 2014, reporting more than 30 discoveries worldwide and adding an estimated one billion barrels of new resources to our holdings,” he added.

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 approximately 140 miles off the coast of Louisiana in 5,183 feet of water. It was drilled to a depth of 33,749 feet. Appraisal drilling will begin in 2015.

“Chevron’s leading position in the Gulf, where we are expecting further growth in the near-term from recent project startups at Jack/St. Malo and Tubular Bells, is further underpinned by this discovery,” said Jeff Shellebarger, president, Chevron North America Exploration and Production Company.

He noted that Chevron currently has five deepwater drillships operating in the Gulf, two of which are focused on exploration activities.

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%).
