Genetic Potential Evaluation of Source Rocks in Masjed Soleiman Oil Field

In the present work ۳۵ cutting samples from ۵ oilwells of Masjed Soleiman oilfield have been pyrolysed by Rock- Eval۶. Results indicate that the Kazhomi, Garu and Sargelo Formations have high TOC and Tmax values, passed diagenesis stage and therefore, have high hydrocarbon generation potential. vanKrevelen diagram demonstrating the studied formations shows type III kerogen for the Sargelo Formation and mixed type III/II kerogen for the rest of the formations. The Sargelo Formation with Tmax up to ۴۸۱°C not only crossed the oil window but also has reached the wet gas generating stage. Total Organic Carbon and Tmax increase from northwest to southeast and also prove the increase in hydrocarbon genetic potential of the Masjed Soleiman oilfield.
