BP has struck oil at the Guadalupe prospect 180 miless off the coast of Louisiana in the deepwater U.S. Gulf of Mexico.

The company said the discovery well, on Keathley Canyon Block 10, was drilled by operator Chevron on behalf of the Guadalupe co-owners. The well encountered significant oil pay in Paleogene age Wilcox Sands.

Located about 180 miles off the Louisiana coast in 3,992 feet of water, the well was drilled to a total depth of 30,173 feet. More tests are being conducted on the well and additional appraisal activity will be needed to determine the extent of the resource.

BP has previously made three discoveries in the emerging Paleogene trend in the deepwater U.S. Gulf of Mexico: Gila in 2013, Tiber in 2009 and Kaskida in 2006.
