Abstract:
The basic objective of the study is to get preliminary understanding of the
subsurface structural trend and stratigraphy of the cited area. Seismic data interpretation
eventually resulted in outcomes as time and depth contour maps. Pirkoh area is a part of
Potwar sub-basin of the Middle Indus Basin of Pakistan. It is an anticlinal closure
bounded by a Main Thrust Fault and its Back Thrust Fault that were generated as a result
of collision of the Indian and the Afghan Block which is proved by using the 2D move
software for structural restoration work. Seismic lines were shot by OGDCL in the year
1981. The seismic lines are dip and strike lines. Seismic line 806-PRK-06/EXT is a strike
line and the others are dip lines. Four reflectors namely Upper Ranikot Formation, Lower
Ranikot Formation, Pab Sandstone Formation, Mughalkot Formation, were marked on
the seismic section on the basis of depth and velocity information of these formations.
Time contour maps of the reflectors were produced using two way time of the reflectors.
RMS velocities were used to find the depths of the formations for the seismic section.
Stratigraphic correlation of wells was done to follow the general trend of lithologies of
Pirkoh area.
