Petrophysical Parameters Estimation Using Geophysical Well Log Data of Indus Sub-Basin Area, Pakistan

The purpose of this paper is to estimate the petrophysical parameters based on geophysical well data to identify hydrocarbon bearing zones in the Indus sub-basin’s area’s Sembar formation. The logging data gamma ray, spontaneous potential, resistivity, neutron and density have been utilized. The Archie’s equation was used to estimate petrophysical parameters. The findings have shown five main prospective zones having good porosity and high movable hydrocarbon saturation. All the reservoir zones have low bulk density and shale volume was comprised between 4.1 to 5 %.
