| Abstract: | By means of the Laplace Transform Methods, this paper offers a complete mathematical treatment of the flow problems about the slightly compressible fluid in the homogeneous formation based on the theory of Bes-sel's functions. It is concerned with wellbore storage and skin effect. It is a complement of the Agarwal's analytic solutions.A complete analytical treatment of the approximating solutions of the early and later pressure performance equations is also given. This paper is an aid to understand the theory of modern well-test and creates the conditions for typical curve match of computer model. |
