ABSTRACT: Assessment of Undiscovered Oil and Gas Resources of the Burgos Basin Province, Northeast Mexico
The U.S. Geological Survey (USGS) recently completed an assessment of the undiscovered oil and gas potential of the Burgos Basin Province of northeastern Mexico. The Burgos Basin Province, as defined for this assessment, was bounded on the north by the U.S.-Mexico border, on the west by the Tamaulipas, Pichachos-Peyote, and El Burro-Salado uplifts, on the south by the northern boundary of the Tampico-Mislanta Basin, and on the east to include the Mexican Ridges and part of the Perdido fold belt in the deep-water Gulf of Mexico. The USGS defined an Upper Jurassic-Cretaceous-Tertiary Composite Total Petroleum System (TPS) and five Assessment Units (AU) within the TPS, and estimated a mean of 12.9 trillion cubic feet of non-associated gas, a mean of 6.2 billion barrels of oil (with 7.4 trillion cubic feet of associated gas), and a mean of 0.52 billion barrels of natural gas liquids for the five assessment units. The onshore portion of the Burgos Basin Province was estimated to contain nearly all of the undiscovered non-associated gas resource. The undiscovered oil resource was postulated to be mostly offshore, mainly in Eocene sandstone reservoirs within compressional structures associated with the Mexican Ridges and with the southward extension of the Perdido fold belt. The assessment of oil (and associated gas) in the offshore is highly uncertain, but relied on recent discoveries in the U.S. portion of the Perdido fold belt, including discoveries in the Trident and Great White prospects.
