Abstract
The goal of this paper i s to show a numerical method for evaluate distance a t an imoemeable barrier, usinq buildup and dradown pressure t e s t analysis. This technical needs of derivates evaluation i n transition zone defined between two classics semilog straiqht l i n e s with slopes "m" and "219" that are present in these systems. Complementary to shis study the authors ProDose type curves for application i n a1 ternatives analysis. An illustrative example i s showed using the proposed method.
