        The results obtained from Rock-Eval pyrolysis and measurement of TOC showe that Gourpi and Pabdeh formations in Binak well show that Source rock does not have the sufficient organic material to produce hydrocarbons. However,Gourpi and Pabdeh in formations Hendijan and Doroud wells support the organic material to produce hydrocarbons and are placed in a more appropriate stage in terms of production. Samply from Binak Lack Contamiaton and or staining Lokite Source rock Samples from Hendigan and Doroud wells show contamination and Staining to migration from other interuals. Source rock show type II taype II-III in Binak and which the samples are n ot fully matured (the end of diagenesis) and the Kerogen for Source rock type of in Hendijan and Doroud wells is II and II-III respectively traversing maturing pathway by reaching catagenesis stage and reaching at the beginning of oil generation window. In terms of the type of organic matter, most in studay wells are located in oil zone and the maximum production potential is associated with Doroud well Location so that it could serves as a production source rock. Although, the Hendijan well have high yield potential, due to failure to reach to oil generation window it fails in producing oil. Sedimentation in the Binak well is done quickly and in oxidized condition and OM preserved partially. The Hendijan and Doroud wells show medium sedimentation in restricted condition and quick sedimentation in oxidizing environment respectively indicating Marine depositinal environment Manuscript profile

        In order to analyze the geochemical characteristics, the oil samples of the Asmari reservoirs and the Bangistan group in the Kopal field were studied using various geochemical techniques such as asphalting technique, gas chromatography technique, gas chromatography-mass spectrometry technique and carbon isotope measurement technique, were subjected to analysis. the purpose of This research is a comparison of carbon isotope and geochemical properties of Asmara and Bangestan oils in Kopal field to determine their parent rock and origin. Considering the results of the testing technique and analysis of biomakers of the esteranes and terpanes family extracted from saturated cutting, it can be stated that the oils accumulated in the Asmari and Bangestan reservoirs of the Kopal field have the characteristics of oil. are paraffinic, which indicates the existence of light oil with good quality, mature, low viscosity and high sulfur. By placing the ratio of biomarker parameters against carbon 13 isotope and examining the general results of the graphs, it was found that the oil samples of Asmari reservoirs and Bangestan reservoirs in the studied field are from a common generative rock. have been found and have the same characteristics and only slightly differ in maturity, degree of fluidity, and the amount of migration processes between the source rock and the reservoir rock, and similarly, the transformation course of the source rock organic materials has occurred naturally in the Copal field. The values of carbon isotopes in the oils indicate the average maturity of the rocks producing the oils. The graph of the ratio of the aromatic carbon 13 isotope against the saturated carbon 13 isotope showed that both field oil samples The subject of study belongs to marine environments.
