The purpose of this work is to calculate Surge and Swab pressures in eccentric wells. Analysis of the phenomenon, in which fluid is confined between two eccentric cylinders, are made. Conformal mapping calculations is used to lead the original eccentric domain into equivalent concentric domain, since usual models only make calculation for concentric geometries. The results of this study, using the proposed methodology, are presented and discussed.
