2D Seismic Interpretation and Petrophysical Analysis of Khushalgarh Area, Upper Indus Basin, Pakistan (P-1210) (MFN 5946)

Abstract

This thesis presents the 2D seismic interpretation of Khushalgarh area in Upper Indus Basin. The Area is related to the North Potwar deformed zone (NPDZ) as a part of active fold and thrust belt formed by the Indo-Eurasian plate collision. The aim of this study is to re-evaluate the area to estimate the potential for discovery of hydrocarbons. Data used for seismic interpretation consist of four seismic lines 86-KH-22, 86-KH-23, 86-KH-24 and 86-KH-98. The tops of two reflectors have been marked on seismic sections, namely Kohat and Kuldana formations. As the study area lies in the compressional tectonic regime, hence, the interpreted faults were marked as thrust faults. In Jalwal-01 well, two zones of interest have been marked within Kohat Formation for petrophysical analysis. The average water and hydrocarbon saturation in zone 1 were81.45% and 18.54%, respectively. In zone 2, average water and hydrocarbon saturations were73.84%and 26.15%, respectively. Higher saturation of water and lower effective porosity in each zone were the reason why well went dry.
