HOUSTON – Walter Oil & Gas Corp. has announced the installation of the recently completed Coelacanth field platform at Ewing Bank block 834 (EW 834) in the Gulf of Mexico.

The 1,312-ft (400-m) tall, conventional four-leg, nine-slot platform is the third-largest fixed conventional platform in the GoM and was built in Gulf Marine Fabricators’ yard in Ingleside, Texas. It required over two million man hours to complete.

After a two and a half-day process of loading the platform’s 60,000,000-lb jacket onto the launch barge, sail-away took place on Oct. 15, 2015.

The Coelacanth field is in approximately 1,200 ft (366 m) of water and spreads across four GoM outer continental shelf blocks: EW 834, EW 835, EW 790, and Mississippi Canyon 793, approximately 125 mi (201 km) south of New Orleans.

The field will produce from two geo-pressured reservoirs below 20,000 ft (6,096 m) on the north side of a salt structure. The Coelacanth platform is designed to produce 30,000 b/d of oil and 60 MMcf/d of gas, and is expected to serve as host for future discoveries in the area.
