THE TIMING AND INCIDENCE OF EXPLORATORY-DRILLING ON OFFSHORE WILDCAT TRACTS

This paper documents exploratory drilling activity on offshore wildcat oil and gas lenses in the Gulf of Mexico sold between 1954 and 1980. We calculate the empirical drilling hazard function for cohorts in spe cific areas. For each year of the lease, we study the determinants of the decision whether to begin exploratory drilling and their relations hip to the outcome of any drilling activity. Our results indicate that equilibrium predictions of plausible noncooperative models are reason ably accurate and more descriptive than those of cooperative models of drilling timing. We discuss why noncooperative behavior may occur and the potential gains from coordination.
