Exxon Mobil Corporation began production in the deepwater Gulf of Mexico at Hadrian South with facilities tied back to the nearby Lucius project, reducing additional infrastructure requirements.

Daily gross production from Hadrian South, ExxonMobil’s deepest subsea tie-back in nearly a mile and a half of water, is expected to reach approximately 300 million cubic feet of gas and 3,000 barrels of liquids from two wells, the company informed.

Hadrian South is a subsea production system with flowlines connected to the Anadarko-operated Lucius truss spar, which started production in January. With the startup of Hadrian South and Lucius, ExxonMobil’s total Gulf of Mexico net production capacity has increased by more than 45,000 oil-equivalent barrels per day. ExxonMobil holds a 46.7 percent interest in Hadrian South and a 23.3 percent interest in Lucius.

“Successful deepwater projects like this are a result of ExxonMobil’s disciplined project execution capabilities and commitment to developing quality resources using advanced technology,” said Neil W. Duffin, president of ExxonMobil Development Company.

“Cooperating closely with Lucius operator, Anadarko, has facilitated the development of a deepwater resource that may not have been possible using a standalone approach,” Duffin said. “Developing Gulf of Mexico oil and gas resources creates jobs, generates revenue and supports American energy security.”

Hadrian South is located approximately 230 miles offshore in the Keathley Canyon area of the Gulf of Mexico in about 7,650 feet of water. The discovery well, Hadrian-2, was drilled in 2008 and the appraisal well, the Hadrian-4 sidetrack, was completed in 2009.

ExxonMobil operates Hadrian South; co-venturers Petrobras and Eni hold 23.3 percent and 30 percent, respectively.
