Abstract: 

Despite the fact that kerogen decomposition has not been yet very well understood, it is possible to obtain kinetic parameters which correlate with both empirical and natural geologic data by pyrolysing samples in closed and open systems. In this study, in order to determine hydrocarbon source rocks kinetic parameters, synthetic maturation by using open pyrolysis system (Rock-Eval) was used. In order to determine the equation of the real pyrolysis temperatures, the Rock-Eval pyrolysis oven was calibrated against three standard samples. Three source rock samples from three well known Iranian source rock formations namely Pabdeh, Garu and Kazhdumi were anafyzed at temperature rates of 25, 15, 10 and 5°c/min and their kinetic parameters including activation energy distribution, Arrehnus coefficient and the amount of generated hydrocarbon were determined.
