Abstract:
The main theme of the research emphasis on the 2D seismic interpretation of the study
area in order to delineate the petroleum system and the structures proficient to hydrocarbon
accumulation with the help of available seismic lines. Geographically, the area lies in
Attock District, Punjab, Pakistan. Tectonically, the area lies in eastern Potwar division of
Upper Indus Basin Pakistan. The subsurface image of the area confirms the presence of
anticlinal geometry and pop-up structures. The results are further discussed in detail by
time and depth contour maps’ aid. This document also discusses the petrophysical analysis
of the study area on the basis of well log data available for Oxy-Khaur 01 well drilled in
the field. The main focus of petrophysical analysis is the evaluation of the primary
reservoirs in the study area. The primary reservoirs in this specific well were recognized
as Chorgali Formation and Sakesar Limestone of late Eocene age in terms of three main
reservoir characteristics i.e., porosity, hydrocarbon saturation and shale content of the
reservoirs in the study area. The calculated results show less volume of shale percentage
and good effective porosities on average in both formations so both formations were
considered as potential reservoirs.
