Production has begun at the Delta House semisubmersible floating production system operated and partly owned by LLOG Exploration Co. on Mississippi Canyon Block 254 in the Gulf of Mexico.
LLOG plans to have eight wells online from several hydrocarbon deposits by yearend. The FPS, in 4,500 ft of water, can handle production of 100,000 b/d of oil, 240 MMcfd of natural gas, and 40,000 b/d of water.
Designed by Exmar Offshore, the semi can accommodate 20 risers, producing from as many as nine fields with dual flowlines.
A joint venture of privately owned LLOG and Blackstone Energy Partners holds majority interests in the subsea wells flowing into the Delta House facility. The seven companies with interests in the producing leases don’t own 100% of the FPS and pay fees to the ownership group.
The Delta House FPS is similar to an Exmar semi on Who Dat field operated by LLOG on Mississippi Canyon Block 547. Who Dat, in 3,000 ft of water, began producing oil and gas in December 2011 (OGJ Online, Dec. 21, 2011).
LLOG, Covington, La., recently reported production at Who Dat of 32,000 b/d of oil and 42 MMcfd of gas and said three wells were being drilled.
The Who Dat FPS has capacities of 60,000 b/d of oil, 150 MMscfd of gas, and 40,000 b/d of water.
