Depositional Environment Study of the Pabdeh Formation in Zeloi Oilfield using data obtained by Rock Eval 6 pyrolysis

The purpose of this paper is to study the depositional environment of the Pabdeh Formation in Zeloi Oilfield, northern Dezful Embayment using data obtained by Rock Eval 6 pyrolysis. For that, 36 samples were selected from well number ZE5, which is located in the central part of the field, and analyzed by Rock-Eval 6. For the first time by geochemical methods and on the basis of Tmax and S2 values, this formation has been divided into three zones A, B and C. Zone B with higher TOC and S2 values has more hydrocarbon potential which is related to sea progressive time. The parameter S1+S2 versus TOC shows that production potential of this formation has wide variation and is within the ranges of poor to very good and in general has high potential. The diagram
