The Grand Isle 16/18 field was discovered in 1948 by Humble Oil and has multiple targets with a large area of deep exploratory potential. It is located 7 miles offshore of Lafourche Parish, Louisiana in approximately 50 feet of water. The field consists of two separate shallow piercment salt domes. Pleistocene through Miocene sands are trapped structurally and stratigraphically from 6,000 feet to 13,000 feet against the salt piercments. The field has produced in excess of 515 million BOE since first production, making it the 4th largest oil producing field on the Gulf of Mexico shelf.
