The purpose of this work is to calculate Surge and Swab pressure in oil wells with eccentricity between drill string and wellbore here or casing string.Analysis of this phenomenon, in which the fluid is confined between two eccentric cylinders, are made.The conformal kt196 torque converter mapping is used to lead the eccentric domain into the concentric domain, since the usual models correspond to concentric geometries.

The results of this study, using the proposed methodology, are presented and discussed.
