Chevron recently announced a significant oil discovery at the Anchor prospect in the deepwater US Gulf of Mexico. The Anchor #2 Well, located in Green Canyon Block 807, was drilled to a total depth of 33,749 ft and encountered significant high-quality pay in multiple Inboard Lower Tertiary Wilcox Sands. The Anchor discovery well is located approximately 140 miles from the Louisiana coast in 5,183 ft of water. Appraisal drilling will begin in 2015.
Chevron is the operator, with a 55% working interest in the Anchor prospect. Anchor co-owners are Cobalt International Energy (20%), Samson Offshore Anchor (12.5%) and Venari Resources (12.5%).
“The Anchor discovery, along with the previously announced Guadalupe discovery, are significant finds for us in the deepwater Gulf of Mexico,” Jay Johnson, Senior Vice President, Chevron Upstream, said. “We had one of our best years with the drill bit in 2014, reporting more than 30 discoveries worldwide and adding an estimated 1 billion bbl of new resources to our holdings.”
Anchor is Chevron’s second discovery and Cobalt’s fourth significant subsalt discovery in the deepwater Gulf of Mexico.
“The Anchor discovery well is clearly one of the best wells we’ve drilled to date in the deepwater Gulf of Mexico,”James W. Farnsworth, Cobalt’s Chief Exploration Officer, said. “This exceptional discovery is the result of many years of hard work to identify and mature this exciting prospect and to successfully acquire and unitize the Anchor leases. I am so proud of the entire Cobalt team whose efforts resulted in this exciting discovery.”
Also in the deepwater Gulf of Mexico, Cobalt anticipates spudding the first appraisal well on its North Platte Inboard Lower Tertiary discovery in the Q1 2015 with the newbuild Rowan Reliance drillship. This appraisal well will be drilled in Garden Banks Block 959.
