A single-phase reservoir simulation method has been developed based on a roughly distributed and highly permeable fracture network model to address production and reinjection problems. This method provides effective estimates of reservoir productivity during active explorational and developmental projects. Comparisons with analytical solutions and a representative reservoir simulator support the method's validity, and behavior of original features generated from the numerical solutions is investigated. Such model features include changes in pressure and tracer mass fraction in a highly heterogeneous pore distribution, as well as thermal decay of thermo-sensitive tracers.
