| Abstract: | Using a new point of view, this paper provides a mathematical model that assumes the drawdown distribution of variable-rate case of a single-well system in infinite, isotropic formation, taking wellbore storage and skin effects into consideration. The model gives an accurate analytical slution to the change in bottom-hole pressure, using Laplace's transform method, and gives its dimensionless form so as to draw a typical curve for well-test analysis easily in practice. This paper also briefly presents the method of applying the accurate analytical solution. |
