ExxonMobil Corp. has started production in the deepwater Gulf of Mexico from Hadrian South field, where gross output will reach 300 MMcfd of gas and 3,000 b/d of liquids.

Gross production from the field—the company’s deepest subsea tie-back in a mile and a half of water—is expected to reach 300 MMcfd of gas and 3,000 b/d of liquids from two wells.

Hadrian South is 230 miles offshore in the Keathley Canyon area in 7,650 ft of water. The Hadrian-2 discovery well was drilled in 2008 and the Hadrian-4 sidetrack was completed in 2009.

A subsea production system with flowlines is connected to the nearby Anadarko Petroleum Corp.-operated Lucius truss spar, reducing additional infrastructure requirements. Lucius, where ExxonMobil holds 23.3% interest, started production in January (OGJ Online, Jan. 19, 2015).

Net production from Hadrian South and Lucius will reach more than 45,000 boe/d. Gas transport from the fields is supported by a long-term agreement with Williams Partners, operator of the newly launched Keathley Canyon Connector (OGJ Online, Feb. 20, 2015).

“Cooperating closely with Lucius operator, Anadarko, has facilitated the development of a deepwater resource that may not have been possible using a standalone approach,” commented Neil W. Duffin, president of ExxonMobil Development Co.

ExxonMobil operates Hadrian South with 46.7% interest. Partners are Eni SPA 30% and Petroleo Brasileiro SA (Petrobras) 23.3%.
