Further Information

The reservoir simulator described in this paper has the capability of automatically determining parameter values of reservoir properties in specified zones that will best match observed data. The observed data can be grid cell pressures, water-oil ratios, gas-oil ratios and flowing well bottom hole pressures. A modified Gauss-Newton approach is used that significantly reduces the computational time in generating new parameter estimates. As a test problem, the Second SPE Comparative Problem which is a numerically difficult three phase coning problem, was chosen. The proposed algorithm was able to converge to the original values of permeability and porosity from a wide range of initial guesses and the computational effort was equivalent to performing a few typical simulator runs.
