Archie equation petrophysics topics: porosity, density, well logging pages the archie equation-water saturation as a decimal fraction-resistivity of the 100% water saturated rock. Archie's laws extended to shaly rocks the extensions of the archie resistivity equations for formation factor and water saturation to the case of shaly sands has been undertaken by many. The equations, which are known as the archie equations, relate the resistivity of a formation to the resistivity of the fluids saturating a formation, the porosity of the formation and the.
