ABSTRACT: Giant Oil Fields of the Gulf Coast Area

The 134 giant fields in the Gulf Coastal area contain 29% of the total giant-field reserves. Cumulative production is 32% of the giant-field cumulative total and 20% of the United States cumulative production. Eighty-nine of the giant fields are in the onshore Gulf Coast area with 53% of the reserves, 33 of the fields are offshore with 22% of the reserves, 11 fields are in east Texas with 24% of the reserves, and 1 field is in Florida with 1% of the reserves. In 106 of the giant fields the primary producing interval is Cenozoic with 65% of the reserves, and in 28 giant fields the producing interval is Mesozoic with 35% of the reserves. The primary producing interval in 124 giant fields consists of clastics with 91% of the reserves, in 7 fields the primary lithology is carbonates with % of the reserves, and in 3 giant fields the lithology is mixed clastics and carbonates. A total of 127 fields are in structural traps with all of the reserves, 4 fields are stratigraphic traps (3%) with 18% of the reserves, and 3 fields are combination traps with 1% of the reserves. Over 50 of the giant oil fields in structural traps are salt domes. The most prevalent types of giant fields in the Gulf Coastal area are onshore structural traps with Cenozoic clastics as the primary producing intervals.
