Abstract

In order to produce and develop hydrocarbon fields, understanding of the exact nature of the reservoirs is necessary. Various criteria have been taken into consideration in the zonation of reservoirs and reservoir intervals to separating net and non-pay intervals. Separating the reservoir based on rock type concept can fix the geological disadvantages of conventional zonation methods based on lithology or sedimentological facies. In this study, five Rock Types have been achieved in carbonate-evaporates of Kangan and Dalan formations from the standard Winland Method with Winland’ s coefficients. Modified coefficients have been resulted in the determination of four Rock Types. Results have been showed that determining the Rock Types based on standard Winland Method produces a huge error so that the pore sizes will be three times larger than the real values. Therefore, rock typing with new presented coefficients increases the precision of the calculations and better understanding of the reservoir nature. Integrating these data with thin section studies shows that dolomitization and dissolution are two important diagenetic processes that change reservoir properties in these determined Rock Types.
