dc.description.abstract Migrated seismic lines 884-CW-102, 884-CW-103, 782-CW-13, and 782-CW-30 of Chak Naurang area were obtained from the Directorate General of Petroleum Concessions (DGPC) for seismic interpretation and Well Logs of well Turkwal Deep-01 were obtained for petrophysical evaluation. Most seismic lines are oriented NW-SE of the Potwar foreland basin except for the seismic line 884-CW 103 which is oriented NE-SW. The information we required was given within the time section, which was helpful in the conversion of the time section into depth section. These calculations helped in subsurface interpretation of the area, which was the basic purpose of this project. Four reflectors were marked with Chorgali Formation (Top Eocene), Sakesar Limestone, Khewra Sandstone, and Salt Range Formation. Faults were marked, and then time contour maps were generated. After that time sections were converted into depth sections with the help of average velocity and finally depth contour maps were generated, this helped to know the basic mechanism of the tectonic movement in the area. The major cause is the thrust faults in the area that invoked from the basement salt movement and as a result formed anticlines. Hydrocarbon traps were most possibly developed in these anticlines and are the prospective zones for hydrocarbon accumulation in the Chak Naurang area. A petrophysical evaluation of well Turkwal Deep-01 was carried out to highlight the reservoir area which included the selection of zone of interest followed by Log interpretation. The volume of shale, sand, and porosity was interpreted. On the basis of the Petrophysical Evaluation, it was noted that the carbonate reservoir had dominant secondary porosity while devoid of hydrocarbons, and the reservoir of Cambrian (Khewra Sandstone) bore good porosity but it was also devoid of hydrocarbons. All these conditions made the well very uneconomical so it was abandoned. en_US
