Mead, H N

A new concept for transient pressure behavior is presented whereby in a producing well the total pressure drawdown from the radius of drainage to the well-bore is divided into two parts: (1) the pressure drop from the drainage radius to the wellbore (described by Darcy's Law and the basic buildup equation) and (2) the pressure drop near the wellbore which is caused by an end effect phenomenon called ''skin'', which is the result of possible turbulent flow, damage by various causes as a result of drilling and completing the well, and the percentage of the reservoir that has been perforated or open for production. The methods for determining m and the calculated distance to the effective drainage radius at the time of shutin are empirical. 9 refs.
