AbstractThe process described and tested in this thesis uses systematic zonation based on geological knowledge. First, properties from an actual basin were used to generate a synthetic test basin. Simulations were run to study the effects of the use of the geometric mean for boundary calibration and to assure a bias-free estimation. An investigation of an optimum transmissivity based on an MSE value was conducted, showing that although a transmissivity might produce a small MSE there was still bias in the boundary conditions. The ability of the geometric mean to represent a homogeneous basin regardless of the sample numbers was studied. Use of kriging was compared with the proposed method and it was shown that kriging did not provide a better estimate when calibrating a flow model.
