Abstract
Summary
Evaluation of water saturation is one of the critical parameters in reservoir engineering and as the primary source, petrophysical log data is used in evaluation of water saturation in the reservoir. The main goal in this study is to revise the most commonly used practical correlations for cementation factor with our 571 data set from 45 different wells in South West of Iran. Moreover, by comparing the correlations for interpreting petrophysical logs in a sample well, we concluded that in the formations in high porosity range, there is no significant difference in water saturation calculation between different correlations. But for low-porosity formations, the difference is very noticeable.
