More oil for Chevron in Gulf of Mexico

Chevron has made a significant oil discovery at its Anchor prospect in the Lower Tertiary Wilcox Trend, in the U.S. Gulf of Mexico.

In a press release on Thursday, Jay Johnson, executive vice president Upstream, at the California-based oil company, said that the positive results of the company’s appraisal work at Anchor indicate a significant discovery of potentially hub class scale.

The original Anchor discovery well, located in Green Canyon Block 807, approximately 140 miles (225 km) off the coast of Louisiana in 5,180 feet of water (1,579 m), was drilled in late 2014 to a depth of 33,750 feet (10,287 m) and it encountered 690 feet (210 m) of net oil pay.

According to Chevron, the appraisal drilling began in June 2015, and recently found 694 feet (211 m) of net oil pay. To date, Chevron says it has confirmed a hydrocarbon column of at least 1,800 feet (549 m) in the Lower Tertiary Wilcox reservoirs at Anchor. Complete appraisal of the field will require further delineation wells and technical studies, the company added.

Jeff Shellebarger, President, Chevron North America Exploration and Production Company said: “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.” 

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