Importance of unconformities to oil occurrence in montana...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....
A bayesian procedure for resource evaluation of petroleum provinces in the early stages of exploration... Following a survey of the existing quantitative methods for petroleum resource evaluation, this paper describes a new method for Bayesian updating of discovery probabilities corresponding to a rough field size classification in the light of current dry hole data....
