Abstract:
The main purpose of this study is to evaluate the hydrocarbon potential using
well log data of Panairi-01, Sanghar North, Lower Indus basin, Pakistan. The above
mentioned well is exploratory. The target horizon is Lower Goru Formation of
Cretaceous age. The volume of shale throughout the Formation is high, so the region
where gamma ray readings are low, one zone is marked for evaluating the
hydrocarbon potential. Various petrophysical properties like porosity, resistivity,
volume of shale, are calculated through different logs suites. The average value of
volume of shale is found 46.91 %, effective porosity is 5.79% and saturation of
hydrocarbons is 7.07%. The net pay thickness of prospect zone of Lower Goru
Formation is 79 meters respectively. On the basis of calculated parameters through
petrophysical analysis, it is concluded that in Panairi-01, Lower Goru Formation is
showing very low hydrocarbon saturation.
