This paper was prepared for presentation at the 2nd Saudi Meeting on Oil and Natural Gas Exploration and Production
Technologies (OGEP 2010) held at the King Fahd University of Petroleum & Minerals (KFUPM) Campus in Dhahran,
Kingdom of Saudi Arabia, December 18-20, 2010.
Determination of hydrocarbon saturation is the vital parameter in oil reserve calculation
processes. Archie's formula is the water saturation model for the determination of hydrocarbon
saturation. The parameters of Archie's formula (a, m and n) are determined through laboratory
core analysis program. Determination techniques of Archie's parameters are relatively well
known and validated for sandstone reservoirs. But in case of carbonate rocks, there are
considerable variations in texture and pore type, so, Archie's parameters become more sensitive
to pores pattern distribution and lithofacies properties. Uncertainty in these parameters will
lead to non acceptable errors in the water saturation values.
In this study three techniques are presented to determine Archie's parameters using carbonate
