Petrophysical analysis of Meyal-10 well, western Potwar basin, Pakistan (P-0890) (MFN 3983)

Abstract

Meyal-10 is located in northern Punjab and administratively lies in Meyal village of Pindi-Gheb, Tehsil of District Attock. Tectonically well lies in Western Potwar plateau, Upper Indus Basin. Northern and southern boundaries of Potwar plateau are marked by MBT and SRT respectively, while eastern and western boundaries are marked by left lateral Jhelum Fault (JF) and right lateral Kalabagh Fault (KBF). For petro physical analysis of Meyal-10 well log data along with well tops have been acquired from the Department of Earth and Environmental Sciences, Bahria University, Islamabad. Using well log and tops data zones of interests have been marked i.e. the possible reservoir zones, followed by their detailed analysis while calculating volume of shale, density, neutron and sonic porosities and resistivity of water has been calculated for water and hydrocarbon saturation of reservoir zones, finally net pay zone has been identified based on different cut offs of shale volume, effective porosity and water saturation. Whole research study of Meyal-10 indicates presence of four possible reservoir zones in Sakaesar, Nammal, Upper Rani Kot and Lockhart limestone sealed by the shales of Patala and Chorgali formations.
