2D Seismic Interpretation And Petrophysical Analaysis Of Khaur Area, Upper Indus Basin, Pakistan

Abstract

The present study was conducted to identify the structure and evaluate hydrocarbon potential by using the seismic and well-log data of the Khaur area, Upper Indus Basin, Pakistan. Khaur area lies near Chakwal District of Punjab region in the Potwar basin region of Upper Indus Basin Pakistan. The Potwar sub-basin is situated at the northern margin of Pakistan in the western foothills of the Himalayas. It comprises the Potwar plateau, the Jhelum Plain, and the Salt Range. Khaur structure is thought to be enriched by potential hydrocarbon on the basis of structural and petroleum system studies. Reservoir was marked on seismic data by a time-depth chart using average velocities. Time depth and velocity contour maps of Sakesar Limestone were generated which confirmed the Pop-up structures in the subsurface. It is concluded that the Chorgali Formation and Sakesar Limestone are good reservoirs based on the high effective porosity and low volume of shale, but it have high water saturation so it is not economical.
