The Sedimentary Petrography Of The Oil And Gas Producing Horizons In Montana, Patrick J. Donahue
The Sedimentary Petrography Of The Oil And Gas Producing Horizons In Montana, Patrick J. Donahue
Bachelors Theses and Reports, 1928 - 1970
Montana is an excellent oil province, as oil and gas are produced from a wider range of beds in the geologic section than in any other district in the United States. (1,864) Commercial fields have been developed in Ordovician, Devonian, Mississippian, Pennsylvanian, Jurassic, Lower Cretaceous, and Upper Cretaceous. It is believed that by describing the physical characteristics of the producing horizons, and by placing this information in one compact volume, a better understanding of oil and gas occurrence in Montana may be gained.
