Importance Of Unconformities To Oil Occurrence In Montana, Robert E. Evenson

Bachelors Theses and Reports, 1928 - 1970

Although the majority of geologic structures in Montana have been tested in the search for petroleum, only a few have been found to contain commercial quantities of either oil or gas, and with each successive dry hole, producers are becoming more and more wary of investing capital in new wells located on structural features alone. It is apparent that if new oil and gas fields are to be found in Montana, exploration must be done on the basis of some­thing other than structure, or combined with structure.
