In the present work, the experimental curves from the flow core test are fitted by means of simple functions previously proposed that are linearized in order to find new relationships between parameters. A Least Square Method leads to a simplified methodology for obtaining the unknown fitting coefficients. A sensitivity analysis is carried out on those coefficients in order to show their influence on the determination of relative permeability curves in water-oil systems by the unsteady method, either at a constant flow pressure, or at a constant injected flow. This technique shows its simplicity, accuracy and speed of calculation.
