Oil Resource Potential of Eocene Limestones in Sulaiman Depression

 SHabib Rahi limestone (primarily) and Plrkoh limestone are judged to be present and mildly to medium mature in the synclinal part of the Sulaiman depression. Stage of maturity and type of kerogen may have generated a gas-undersaturated oil. Based on hard field and laboratory data, volumetric calculation of the source rocks bodies followed by chance factor assessment including the probabilistic method, about 2.2 billion US barrels of oil could be expected as undiscovered potential resource sourcing from these two source rocks; however, this resource assessment is subjective and represents by no means more than an educated guess.
