A complete double?permeability reservoir well?test model that takes into consideration inner and outer boundary conditions is built based on well test analysis research. The corresponding precise solution can be obtained in Laplace space. A new method of well test interpretation in Laplace space is presented. Example application indicates that the proposed method is valid and useful.
