2D seismic interpretation and petrophysical analysis of Qadirpur area, central Indus basin, Pakistan (P-1201) (MFN 6351)

Abstract

The main objective of the study was to carry out petro physical analysis and 2D seismic interpretation of Qadirpur area central Indus basin Pakistan. The purpose has been achieved by utilizing complete suite of wire line logs and the available well data and seismic data. All the reservoir zones were evaluated for the hydrocarbon potential in detail using set of equations and different formation evaluation charts made by Schlumberger. The methodology adopted included measurement of shale volume by employing gamma ray log, estimation of porosity using density and neutron log, estimation of effective porosity, calculation of resistivity of water utilizing spontaneous potential log, evaluation of saturation of water and hydrocarbon saturation using Archie equation. Seismic interpretation is done by the given data and two reflectors are marked on the seismic sections which are Habib Rahi and Sui Main Limestone. Saturation of water and hydrocarbons are 60% and 40% respectively. Average porosity for massive sands are around 13.7% in the prospect area.
