The 1312ft tall, conventional four-leg, nine-slot platform is the third largest fixed conventional platform in the Gulf of Mexico and was built in Gulf Marine Fabricators’ yard in Ingleside, Texas. It required over 2 million man-hours to complete. After a 2.5-day process of loading the platform’s 60 million pound jacket onto the launch barge, sail-away took place on 15 October 2015.
Coelacanth Field is in approximately 1200ft of water and spreads across four Gulf of Mexico OCS Blocks: EW 834, EW 835, EW 790, and Mississippi Canyon 793, approximately 125mi south of New Orleans. The field will produce from two geo-pressured reservoirs below 20,000ft on the north side of a salt structure.
Coelacanth Platform is designed to produce 30,000 b/d and 60 MMcft/d of gas, and is expected to serve as host for future discoveries in the area.
Partners in the project include Walter Oil & Gas (50.5% WI), Ridgewood Energy, as manager for its Funds and for ILX Holdings, LLC (a Riverstone Holdings LLC company) (32.5%WI), Gordy Oil Co. (16%WI) and Houston Energy Deepwater Ventures (1%WI).
