Abstract:
Generally the aim was to understand the tectonics and geology of the Balkasar area
along with the interpretation procedure of migrated seismic sections and to check out
the subsurface structures. As the area is a compressional regime so faults were marked
according to their type and structure they are making. Formations were marked with
the help of Well Balkasar OXY 1. Interpretation was done on the migrated seismic
lines PBJ-04, PBJ-05, PBJ-06 and PBJ-09 of Balkasar area. This data was obtained
from Land Mark Resources (LMKR) by the permission of Directorate General of
Petroleum Concession (DGPC) Islamabad. The general dip direction in the project
area of lines PBJ-04, PBJ-05, PBJ-06 is NW-SE and hence the line PBJ-09 oriented
SW-NE is regarded as strike line. The required information was in time domain which
was helpful in the conversion of time into depth by solving the velocity windows
given in the seismic sections with the help of equation i.e s=vt. These calculations
helped in subsurface interpretation of the area, which was the basic purpose of this
project. Five reflectors were marked named Chorgali, Sakesar, Patala, Lockhart and
Basement. Time and depth contour maps were generated which helped us to know the
basic mechanism of tectonic settings in the area. Generation of Synthetic
Seismogram and Petrophysical analysis were also the part of our project.
