Exact solution of unsteady axisymmetrical two-dimensional flow through triple porous media

This paper seeks for the line source and cylindrical plane source solutions of unsteady axisymmetrical two-dimensional flow through infinite and finite reservoirs with triple porosity. They not only reveal the essential characteristics of fractured reservoirs but also generalize and develop the existing primal results of homogeneous and porous media. Ref. [1] gives the line source solution of unsteady axisymmetrical two-dimensional flow in infinite reservoir with double porosity; in this paper we study the problem of flow through triple porous media.
