Abstract:

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.

Key words: oil reservoir, well testing, mathematical model, bottom-hole pressure
