A computer system and a computer-implemented method for calibrating a reservoir characteristic including a permeability of a rock formation. The method includes inputting a measured product KH of a measured permeability K and a flowing zone thickness H over a plurality of corresponding zones in one or more wells and inputting porosity logs for each measured product KH in each of the plurality of zones obtained from the one or more wells. The method further includes reading a porosity-permeability cloud of data points; calculating, for each zone, a predicted product KH from the porosity log using the porosity-permeability cloud of data points; determining one or more weighting coefficients between the predicted KH and the measured KH corresponding to each zone; and calibrating the measured permeability corresponding to each zone using the one or more weighting coefficients. |
