Advances in After Closure Analysis for Naturally Fractured Reservoirs

Using the theory of impulse testing and principle of<br>superposition, Nolte et al [1] developed a method which<br>allows the identification of radial flow and thus the<br>determination of reservoir transmissibility and reservoir<br>pressure. The exhibition of the radial flow is ensured by<br>conducting a specialized calibration test called mini-fall off<br>test. Benelkadi and Tiab [2] proposed a new procedure for<br>determining reservoir permeability and the average reservoir<br>pressure in homogeneous reservoirs. In this paper, the<br>procedure is extended to naturally fractured reservoirs.
