Most oil and gas leases allow the operator to extend possession for an indefinite period by establishing production in paying quantities. We show how this option to “hold by production” (HBP) stimulates the drilling of many wells that would otherwise be uneconomic. Although such wells may superficially appear to be poor investments, in fact they contribute to shareholder value. We also show, however, that the HBP provision delays the drilling of other economic wells, an outcome that has become a frequent point of conflict between lessees and lessors in this industry. We provide a simple method to value the HBP lease provision as a compound option, and estimate that it has increased the value of typical shale gas leases in the U.S. by 25%-250% in recent years, depending on location. The HBP provision appears very likely to have increased drilling in certain areas, but even more likely to have decreased drilling elsewhere. Understanding the incentives created by the HBP option is fundamental to understanding the rate and pattern of drilling in U.S. shale gas plays. Our analysis does not support industry critics who allege that continued drilling of many sub-marginal gas wells has been a mistake.
