In this study, the Hydrocarbon generation Potential of Kazhdomi and Pabdeh formation in Bangestan Anticline has been studied. In this regard, 10 samples were collected from Pabdeh formation, and 6 samples were collected from Kazhdomi formation that eventually was analyzed by Rock-Eval 6 system. In this system, a temperature raising program in oxygen-free environment was used. This device introduces a series of valuable factors related to Source rock, including: available free hydrocarbon in sample (Peak S1), hydrocarbons emanated From thermal cracking of Kerogen (Peak S2), heat index of organic matter (Tmax), Total Organic Carbon (TOC), Hydrogen Index (HI), Oxygen Index (OI), and Production Index (PI). Applying these factors, there factors of evaluating source rock could be identified, which included amount, type and thermal maturity of organic material. Kerogen of Kazhdomi Formation was type II, and Kerogen of Pabdeh Formation was defined type II and III. Studied showed that Kazhdomi Formation compared with Pabdeh Formation had more oil-generation potential. Sedimentary Facies of Pabdeh Formation was defined C, CD, D and sedimentary Facies of Kazhdomi formation was defined AB, B, BC, and C. The amount of inter organic carbon of Pabdeh formation was estimated 0.9769 weight percent (WP), and this amount for Pabdeh formation was about 0.3957 weight percent (WP). Determination of hydrocarbon absorption by Rock matrix showed that absorption rate in samples of Kazhdomi formation was much more than samples of Pabdeh Formation, which indicates that Rock matrix in Kazhdomi formation involves much more clay mineral compared with Pabdeh formation.
