Evaluation of the inter-porosity exchange coefficient inferred from well test in a fractured reservoir with a non-uniform distribution pattern: A numerical study

Finally the inferred inter-porosity fluid exchange coefficients are compared; it is shown that, in a non-uniformly fractured system, this coefficient value is highly dependent on the fracture distribution pattern, pumping well location and its connectivity to the flow-path network. Consequently, we demonstrate that the standard and classic methods of the average matrix bock dimension estimation by well test may be very sensitive to the pattern of fracture distribution (uniform or non-uniform).
