Production from the development is expected to reach around 300 MMcf/d and 3,000 bbl of liquids from two wells.
Hadrian South consists of flowlines connected to the Anadarko-operated Lucius truss spar, which started production in January.
Hadrian South is located approximately 230 mi (370 km) offshore in the Keathley Canyon area of the GoM in about 7,650 ft (2,332 m) of water. The discovery well, Hadrian-2, was drilled in 2008 and the appraisal well, the Hadrian-4 side track, was completed in 2009.
ExxonMobil operates Hadrian South; co-venturers Petrobras and Eni hold 23.3% and 30%, respectively.
