Applying the corrected Hydrogen Index values obtained from S-2 vs. TOC graph in conjuction with the results of Rock-Eval pyrolysis and mass balance calculations provide estimations of the original hydrocarbon generative capacity and the amounts of hydrocarbons generated. For calculations and a comparison between three different approaches were applied to 27 organic-rich samples collected from the Derekoy Formation shales which are mainly characterized by oil-prone Type-II kerogen that is in different thermal maturity levels. Such calculations indicate that (1) the results of the calculated amounts of original hydrocarbons are mostly over 100,000 ppm, (2) the results of the hydrocarbon generative capacities from two methods which include fractional conversion value are in accordance, and, are over 5000 ppm, and (3) when the fractional conversion values are low (ranging from essentially zero to 0.5%), indicating thermally immature stage, the calculation results of three methods are almost similar.
