Geochemical characterization and evaluation of the hydrocarbon potential of Gurpi in a number of fields Located in North West of Persian Gulf

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
