The Houston-based subsidiary of Elf Aquitaine and its partners have approved construction of a conventional four-leg, 14-slot drilling and production platform to be set in 1132 feet of water. The Virgo platform will be the third largest conventional platform in the Gulf, following Shell's Bullwinkle (Green Canyon block 65) and BP's Pompano (Viosca Knoll block 989). It will be capable of producing 120 million cubic feet per day of natural gas and 15,000 barrels per day of oil and condensates.
