In oil exploration, source rock is considered as the most important main part in a petroleum system for the exploration of hydrocarbon materials. By using gamma, neutron, density, acoustic and specific resistance profiles, analysis and interpretation of the studied wells using the method can calculate the amount of total organic carbon.By using the data of digital recorders and combining them by Interactive Petrophysics (IP) software, we found the areas containing organic carbon in Pabde formation. Laboratory analyzes were used to confirm and verify the upcoming study. Areas with mature source rocks in the Pabde Formation were found by the above-mentioned diggers in the eastern Sosangerd well.According to the sequence repeated by Negar Gamma in all the wells in Pabde formation and by comparing the sequence in these wells, the finding of mature source rock in Mehrd well, which lacked the data of Negar Gamma, only It was realized by using gamma recorder and with the help of this sequence found from other wells.
