Water Resistivity & Formation Factor

One of the most known ways to calculate water saturation is through Archie's equation. This includes certain measurements and values such as formation resistivity- water saturated, porosity, tortuosity factor and cementation exponent. The equation expressed is the following:

Where:
• Ro= formation resistivity- water saturated
• ɸ = porosity
• a= tortuosity factor
• m= cementation exponent
