Geologic comparison of the oil window and dry gas window within the Tow Creek member of the Niobrara Formation in the Piceance Basin of northwestern Colorado, A
The Piceance Basin of northwest Colorado has historically produced significant amounts of oil and natural gas from shallow Upper Cretaceous Mesa Verde Group reservoirs. In the past decade a deeper target has earned attention within the Mancos Shale interval. The Niobrara Formation is a proven resource in the highly explored Denver Basin. More recently it has become a target in western basins, such as, the Sand Wash, San Juan, and Piceance Basins of the Rocky Mountains. Although compositionally the Niobrara differs within the Piceance Basin, production from the interval has taken place in large ...
