Abstract

Many commercial gas and oil reservoirs are composed of fractured reser- voir rock. The fractures provide high flow channels through the reservoir and can add significantly to the reservoir conductivity. However, the in- clusion of the fracture effects is a very difficult modeling task. One of the current methods for modeling fractured reservoirs is the so-called dual porosity model. In this model the reservoir rock is represented by blocks of low conductivity material regularly spaced within a higher conductivity matrix, which represents the fractures. The regular nature of the model and the high connectivity of the fracture components results in a highly nonphysical model. Another popular model ignores the conductivity ef- fects of the matrix rock and only examines the flow through the fracture sys
