The Evaluation of Hydrocarbon Generation Of Kashafroud Formation In

Today, the evaluation of hydrocarbon generation by using the A log R method as a practical method has been successfully applied to many wells worldwide.This method has been presented for prediction of organic richness of source rocks by Passey et al., in 1990 and can be accurate over a wide range of maturities. It is based on the overlaying of a properly scaled porosity log (generally the sonic transit time log) on a resistivity log, determination of separation between the logs, estimation of total organic carbon (TOC) and S2 (quantity of free hydrocarbon released during pyrolysis in Rock-Eval instrument). The organic richness of formations without sampling could be accurately evaluated by using this method. in this paper, the organic richness of Kashafroud formation has been evaluated by using the A log R method in wells 16 and 30 of Khangiran anticline (Kopet-Dagh region) and it has been compared to core samples.
