Abstract:
The main purpose of the thesis is to evaluate the structure and hydrocarbon potential using
seismic and well log data of KalarSyedanarea, Upper Indus Basin, Pakistan. Kalar Syedan
area lies in Potwar sub-basin. The Potwar sub-basin is situated at the northern margin of
the Pakistan in the western foothills of Himalaya. It comprises of the Potwar Plateau, the
Jhelum plain and the Salt Range. Five seismiclinesPR-92-16,PR-92-19,PR-92-21, PR-
92-26 and PR-92-26 of Kallar Syedan area and well logs of KALLAR X-01 of Potwar
Basin were obtained from LMKR with the approval of Directorate General of Petroleum
Concession (DGPC), Islamabad for seismic interpretation and Petrophysical analysis.
Line PR-92-19 is trending N-S while other lines are trending E-W. Seismic lines PR-92-
19 and PR-92-21 are strike lines whereas PR-92-16, PR-92-24 and PR-92-26 are the dip
lines respectively. Velocity information required was given within the seismic sections
that facilitatedus to convert the time sections into depth sections.Conversion of depth
sections is done with the help of average velocities and depth contour maps were
generated.Two reflectors were marked that were of Murree Formation and Kuldana
Formation. Interpretation results show that there are pop up anticline structures with
adjacent syncline in the subsurface. Logging is done up to Murree formation which is at
shallower depth. For Petrophysical analysis a zone have been marked in Murree formation
and volume of shale, sonic porosity, average porosity, effective porosity, saturation of
water and saturation of hydrocarbon is calculated and the result shows that the zone is
water bearing i.e. it contains 80% water and 20% hydrocarbon.
