Why explore for oil when it is cheaper to buy?

Abstract

This article uses results of independent US oil companies to examine their decisions in a high-risk environment. When these companies seek to replace oil production, the available choices fall into two broad classifications, each with its own distribution of expected costs and returns: explore for oil; or buy proven oil reserves. Firms prove risk-sensitive in their decisions as the balance struck between building reserves by acquisition and by exploration responds to firm characteristics. The crossover from risk embrace (exploration) to risk aversion (acquisition) occurs when the probability of success from the more risky strategy drops below about 15%. This matches the behaviour of decision..
