ExxonMobil has made two new oil discoveries and one gas discovery in the Gulf of Mexico.
The KC919-3 wildcat well, the first post-moratorium deepwater exploration well, is located 250 miles southwest of New Orleans, US, at a depth of about 7,000ft.
The well confirmed the presence of a second oil accumulation in Keathley Canyon block 919.
The company encountered in excess of 475ft of net oil pay and a minor amount of gas in Pliocene sandstone reservoirs in the well.
ExxonMobil Exploration Company president Steve Greenlee said that it estimates a recoverable resource of more than 700 million barrels of oil equivalent combined in their Keathley Canyon blocks.
ExxonMobil is the operator of KC918, KC919, KC963 and KC964, holding a 50% working interest.
Petrobras America holds a 50% working interest in KC918, while Eni Petroleum US and Petrobras America each hold a 25% working interest in KC919, KC963 and KC964.
