Abstract	The exactness of water saturation value for given reservoir conditions depends on the accuracy of Archie parameters a, m, and n. The terms of Archie relationship have been subjected to many laboratory investigations and even more speculation. There are many factors that affect porosity exponent m, saturation exponent n, and tortuosity factor a. Usually, assumptions are made to approximate a and m; often m is 2, while a may be 0.81 or 1.0 depending on the type of lithology. But it is very difficult to fix Archie parameters regardless of reservoir characteristics; rock wettability, formation water salinity, permeability, porosity, and fluids distribution. This work illustrates a simple numerical method to calculate a and m which depends on F$_{R}$-R$_{O}$ overlays method which is used as hydrocarbon indicator. The method is tested using synthetic and real data to ensure its ability in determining formation factor parameters a and m.
