Some Considerations in the Valuation of Gas Wells

John D. Wright

Abstract

There are a number of implicit assumptions made during the valuation of a gas well that can have a large effect on the calculated value. A tight gas sand well that has been massively hydraulically fractured has a production signature characterized by high initial rates, extremely rapid early decline, and a pronounced flattening of the rate-time curve at later times. This production profile, when combined with apparently subtle assumptions used in the economic calculations, can lead to significant differences in the calculated value. This paper examines the effect of several of those assumptions.
