Abstract: This paper suggested a mathematical model for well testing with skin
and wellbore storage in a circular closed reservoir, and gave out a solution in Laplace space according to Laplace transform method.Using Stehfest's method for numerical inversion of Laplace transform,we can get the solution in real space easily_These results have been used in our well testing software,
