Oil major Chevron said it has made a “significant discovery” after the appraisal of the Anchor discovery in the Gulf of Mexico.
The original discovery well, which is located 140 miles off the coast of Louisiana, was drilled in late last year to a depth of 33,750feet and encountered 690feet of net oil pay.
The appraisal drilling began in June this year and Chevron said complete appraisal of the field will require further delineation wells and technical studies.
Chevron is the operator of the Anchor prospect with a 55% working interest.
Jay Johnson, executive vice president for upstream said the results indicate a “significant discovery of potentially hub class scale”.
The co-owners are Cobalt International Energy with a 20% share, Samson Offshore Anchor with a 12.5% share and Venari Resources with 12.5%.
Jeff Shellebarger, president for Chevron North America Exploration and Production, 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.”
