Abstract:
Pirkoh Gas field is prolific gas-producing block situated in the Middle Indus Basin in Pakistan. It contains several developments and production (D & P) leases, which are producing gas from Cretaceous rocks. The present study aimed to evaluate the petrophysical properties of the Pab Sandstone using well log data. My study revealed that the reservoir quality sands are deposited in the study area. Well correlation, Petrophysical data logs (PDLs) and lithology identification neutrondensity cross plot techniques were adopted to calculate the petrophysical properties and identification of lithology of the reservoir level. Neutron –density cross plots shows that the major lithology is sand with some portion of shales and shaly sands. Sand packages identified in the Pab Sandstone do have good porosity values and multiple small reservoir intervals have been identified in both the wells having netpay of 7.46 m in Pirkoh-01 and 9.41 m in Pirkoh-32A. The results shows that the Pab Sandstone hold good hydrocarbon saturation.
