West Delta 73 Field

West Delta 73 Field

The West Delta 73 field is located 28 miles offshore of Grand Isle, Louisiana in approximately 175 feet of water on the Outer Continental Shelf (DzOCSdz). First discovered in 1962 by Humble Oil and Refining the field has produced in excess of 389 MMBOE to date. The field is a large low relief faulted anticline. The field produces from Pleistocene through Upper Miocene aged sands trapped structurally on the high side closures over the large anticlinal feature from 1,500 feet to 13,000 feet. This field is the 10th largest oil field in the GoM Shelf, based on cumulative production to date.

West Delta 30 Field

West Delta 30 Field

We operate eight of the twelve blocks that comprise the West Delta Block 30 Field. The field lies in United States Federal waters about 21 miles south of Grand Isle, Louisiana in approximately 20-60 feet of water. The field, which was discovered in 1948 by Humble Oil and Refining has produced in excess of 752 MMBOE to date. The field contains hydrocarbon accumulations set up by a salt dome on the western side of the field and a large counter regional fault running east-west through the middle of the field. Productive sands range from 2,000 feet deep to 17,500 feet deep and generally produce via a strong water drive. Traps contained in the field are both structural and stratigraphic. Minor faulting that is secondary to the major normal fault separates hydrocarbon accumulations into compartments. This field is the second largest oil field on the GoM Shelf, based on cumulative production to date.
