US-based LLOG Exploration, and its joint venture partner Blackstone Energy Group, have started production from the Delta House floating production system (FPS) in deepwater Gulf of Mexico.

LLOG will continue to ramp up production in the coming months by bringing eight wells online by the end of the year.

The Delta House FPS is designed to handle peak daily production of 100,000 barrels of oil and 240 million cubic feet of natural gas.

"First production at Delta House marks a significant milestone for LLOG."

LLOG Exploration president and CEO Scott Gutterman said: "First production at Delta House marks a significant milestone for LLOG.

"Not only do we expect to double our production when all of the wells come online this year, but we are proud to achieve a cycle time of about three years from first discovery to first production for an FPS development project which is among the best in the Gulf of Mexico.

"With continued development at Who Dat and Delta House, coupled with five additional exploratory wells, 2015 stands to be a transformative year for production and reserve growth at LLOG."

Delta House is the second floating production system the company has brought online in four years, since its first FPS, Who Dat, began production in 2011.

The company made the first Delta House discovery in 2012.
