The 1,312 foot tall, conventional 4-leg, 9-slot platform was built in Gulf Marine Fabricators' yard in Ingleside, Texas. Platform construction began in March 2013 and was completed in October 2015. The platform is designed to produce 30,000 barrels of oil per day and 60 million cubic feet of gas per day, and is expected to serve as host for future discoveries in the area.

Coelacanth Field is in approximately 1,200 feet of water and spreads across four Gulf of Mexico OCS Blocks: EW 834, EW 835, EW 790, and Mississippi Canyon 793, approximately 125 miles south of New Orleans. The field will produce from two geo-pressured reservoirs below 20,000 feet on the north side of a salt structure.

Partners in the project include Walter Oil & Gas Corp. (50.5% WI), Ridgewood Energy Corp., 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 LLC (1%WI).
