COVINGTON, Louisiana – LLOG Bluewater, a joint venture between LLOG Exploration LLC and Blackstone Energy Partners, has completed installing the Delta House floating production system (FPS) in Mississippi Canyon 254. The FPS is 130 mi (209 km) southeast of New Orleans in 4,500 ft (1,372 m) of water.
LLOG, as operator, built the hull of the FPS atHyundai Heavy Industry’s yard in Ulsan, South Korea, and the topsides at Kiewit in Ingleside, Texas. ArcLight is the majority owner of the infrastructure consisting of the FPS and the lateral export pipelines. Other owners in the infrastructure include LLOG, Calypso Exploration LLC, Red Willow Offshore LLC, and the entities managed by Ridgewood Energy.
The FPS is designed for peaking capacity of 100,000 b/d of oil and 240 MMcf/d (6.8 MMcm/d) of gas. Most of the infield and export lines and subsea equipment (trees, manifolds, umbilical termination assemblies) are in place. Lead time from sanction to installation was 22 months, and first production from the facility is expected in 1H 2015. The facility will serve as host for LLOG-operated fields in the region.
LLOG and its partner Ridgewood Energy have drilled a successful exploration test at the Mississippi Canyon 79 “Otis” prospect. The initial exploratory well encountered more than 70 ft (21 m) of net hydrocarbons, and a subsequent appraisal side track confirmed the discovery. The Miocene target is apparently a high condensate yield gas reservoir in a high-quality reservoir sand. LLOG owns 70% working interest in the field. LLOG has begun evaluating regional hosts, including the Delta House FPS, regarding subsea development options for the discovery.
LLOG has also recently installed production facilities at its Powerball development at South Timbalier 231/232. LLOG and its partner, Walter Oil and Gas Corp., expect production from the field before year-end. The South Timbalier 231 #1 encountered 92 ft (28 m) of net gas pay and the South Timbalier 232 #1 encountered 190 ft (58 m) of net gas pay. LLOG owns 75% working interest in the field.
In 2Q 2014, LLOG initiated production from its Biddy Ball field at Mississippi Canyon 705 in 1,000 ft (305 m) of water. Biddy Ball joined Mississippi Canyon 751 (Goose) and Mississippi Canyon 707 in a three-well subsea system that is 100% owned by LLOG Bluewater and LLOG Exploration.
