Chevron makes oil discovery in deepwater gulf Anchor prospect

Chevron Corp. reported a discovery of oil pay in multiple Lower Tertiary Wilcox sands in its Anchor prospect’s Green Canyon Block 807 Well No. 2, drilled in the deepwater Gulf of Mexico.

The well, which was spudded in August 2014, was drilled about 140 miles offshore Louisiana in 5,183 ft of water. It reached a depth of 33,749 ft. Chevron says appraisal drilling begins in August.

“The Anchor discovery, along with the previously announced Guadalupe discovery (OGJ Online, Oct. 23, 2014), are significant finds for us in the deepwater Gulf of Mexico,” said Jay Johnson, senior vice-president, upstream. He added that these discoveries, combined with more than 30 others worldwide in 2014, will add an estimated 1 billion bbl of resources to the company’s holdings.

The Anchor well was drilled by Pacific Drilling’s Santa Ana drillship. Chevron says it has five deepwater drillships operating in the gulf, two of which are focused on exploration (OGJ Online, Oct. 17, 2014).

Chevron is Anchor’s operator with a 55% working interest, Cobalt International Energy Inc. has 20%, Samson Offshore Anchor LLC and Venari Resources LLC each have 12.5%.
