Abstract:
The present study was accompanied to delineate the subsurface geology of
Fimkassar area by the structural interpretation of seismic. The
Fimkassar area lies within the Upper Indus Basin in SE of Salt range Potwar Foreland
Basin. The marked horizons are recognized using Formation tops from wells Turkwal-
01 and Turkwal Deep-01. Seismic interpretation of the given 2D Information reveals
that the study area has undergone severe distortion illustrated by the event of thrusts
and back thrusts forming a triangle zone within the subsurface showing a pop-up
geometry. The zones interpreted by the study includes Khewra Sandstone and Chorgali
Formation that could have the most important crude potential within the study area.
Velocity modelling was carried out on all seismic data which gave more
accurate interpolated velocity according to geological cross section of area. The
interpolated velocity was then used in post stack depth and time migration. The
migrated section gave more clear sections with reduced noise and clearer picture of
subsurface i.e., faults and horizons were more visible.
