Wyoming Oil & Gas Basins
WSGS geologists track and record Wyoming's oil and gas production according to each basin. These basins, otherwise known as “Laramide basins,” are fault-bounded basins that formed between basement-cored mountain ranges during the Late Cretaceous to Early Eocene Laramide orogeny (~80–55 Ma). These basins formed by basement-rooted reverse faults with as much as tens of kilometers of vertical offset. Laramide basins are found from northern Mexico through Canada. The primary Laramide basins in Wyoming are the Greater Green River, Wind River, Bighorn, Powder River, Hanna, Denver, Laramie, and Shirley basins.
