The Canyon is rich in oil fields. The major oilfields at the Keathley Canyon are Tiber,[2] Kaskida,[3] Lucius,[4] and Buckskin.[5] Many oil companies, including Chevron Corporation, BP, Anadarko Petroleum, ExxonMobil, Repsol,[6] Shell, Devon Energy, BHP Billiton, Eni, Navitas Petroleum and Total S.A. have leased the rights to drill for oil in this area.[citation needed]

In June, 2011, ExxonMobil announced two major oil and gas discoveries in Keathley Canyon blocks 918, 919, and 964 (Hadrian field)[7] 250 miles (400 km) southwest of New Orleans, with combined estimated reserves of 700 million barrels (110×10^6 m3).[8] The find was "the company’s first deepwater exploration well following a U.S. moratorium" after the Deepwater Horizon explosion and oil spill in the Gulf in 2010 and "one of the largest discoveries in the Gulf ... in the last decade." "Exxon holds a 50% working interest in four ... blocks. Units owned by Petrobras and Eni SPA hold a 25% interest in three of the blocks. Petrobras also owns 50% of one of the blocks."[9]
