Chevron reports successful appraisal of Anchor discovery in deepwater GoM

SAN RAMON, California -- Chevron Corp. has announced the successful appraisal of the deepwater Anchor discovery in the Lower Tertiary Wilcox Trend in the Gulf of Mexico.

“The positive results of our appraisal work at Anchor indicate a significant discovery of potentially hub class scale,” Jay Johnson, executive V.P., Upstream, Chevron Corporation, said.

The original Anchor discovery well, in Green Canyon Block 807, approximately 140 miles off the coast of Louisiana in 5,180 ft of water, was drilled in late 2014 to a depth of 33,750 ft and it encountered 690 ft of net oil pay.

Appraisal drilling began in June 2015 and recently found 694 ft of net oil pay. To date, Chevron has confirmed a hydrocarbon column of at least 1,800 ft in the Lower Tertiary Wilcox reservoirs at Anchor. Complete appraisal of the field will require further delineation wells and technical studies.

“After the success of the discovery well announced earlier this year, we have pursued appraisal work to further evaluate the results and assess development alternatives to optimize value creation,” Jeff Shellebarger, president, Chevron North America Exploration and Production Company, added.

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