Genetic Potential Evaluation of source rocks Masjide-Soleiman oil field
In the present work 35 cutting samples from 5 oilwells of Masjede-Soleiman oilfield have been pyrolysed by Rock-Eval6. Results indicate that, Kazhdumi, Garu and Sargelo formations have high TOC and Tmax values, passed diagenesis stage and therfore, have high hydrocarbon generation potential. Van Krevelen diagram demonstrating the studied formations shows type III kerogen for Sargelo formation and mixed type III/II kerogen for rest of the formations. Sargelo formation with Tmax up to 481?C not only crossed the oil window but also has reached wet gas generating stage. Organic facies changes in Sargelo Formation having low HI in compare to OI indicate oxidizing invironment of deposition. Total Organic Carbon and Tmax increase from northwest to southeast and also proves the increase in hydrocarbon genetic potential of Masjide-Soleiman oilfield.
