Palynology and petroleum potential of the Kazhdumi Formation (Cretaceous: Albian-Cenomanian) in the South Pars field, northern Persian Gulf

Twenty-two samples from the four oil-prone wells were also selected for geochemical analysis using Rock-Eval pyrolysis. Results show that the Kazhdumi Formation at South Pars, in contrast to the Zagros Basin, is gas-prone (predominantly type III kerogen), thermally immature, and poor in terms of hydrocarbon generation. It could not have produced the oil in those oil-prone wells studied.
