LOG PERMEABILITY MODEL CALIBRATION USING RESERVOIR FLUID FLOW MEASUREMENTS

摘要

This invention relates to methods for calibrating a formation permeability model with respect to data obtained from fluid flow measurements. A method according to the invention includes determining a correlation coefficient fo r a porosity - irreducible water saturation relationship; determining a leadin g coefficient for a formation permeability model; and determining at least one exponent parameter for the formation permeability model by minimizing a basi s function that represents a difference between a formation permeability estimate derived from the formation permeability model and a formation permeability estimate derived from the fluid flow measurements.
