Test Results of Stimulated Wells in Devonian Shales

The long test times required to attain radial flow in stimulated Devonian shale gas wells are impractical. However, experience shows that a short test period (about two weeks) is sufficient to evaluate reservoir and fracture properties using conventional techniques followed by mathematical simulation of the observed pressures. History matches, whether unique or not (insufficient production data are available at present to establish uniqueness), give clear insight into reservoir properties, the effectiveness of frac treatment, and well deliverability.
