Fluid saturation is one of the most important parameters that is used to determine the properties of oil reservoirs. In clean formations, water saturation is calculated by Archie's relation. However, in shaly zones, Archie's formula should change, or a new model should be generated that connect saturation with petrophysical parameters of the reservoirs such as the volume of shale, effective porosity and specific resistance. This practical study has used actual well logging data from the field of South West of Iran to evaluate and compare the most popular fore shaly limestone models for calculating water saturation. In this study, water saturation was calculated by Indonesia, Waxman-Smiths, Simandoux models and CEC on Asmari reservoirs in one of the wells of Kupal oil field. The results show that shale volume models calculate the rate of water saturation more than CEC models. In smaller reservoirs zones, the use of CEC models brings results that are more realistic. Asmari formation is the main hydrocarbon reservoir in the South-West of Iran. [ABSTRACT FROM AUTHOR]
