Abstract:
Migrated seismic lines PSM96-114, PSM96-115, PSM98-202 of Sawan area,
which lies in the Central Indus basin, Pakistan, lines were obtained from Directorate General of
Petroleum Concession (DGPC) for seismic interpretation and well logs of well sawan 01 were
also obtained. Main objectives include to delineate the subsurface structure and to locate the
prospective zones in the study area. To achieve these objectives, two seismic lines are strike lines
and one seismic line is dip line.
Five reflectors were marked with Sui main limestone Eocene and Base Formation is
Chiltan of middle Jurassic, in between these Formations three more formations are marked ;
Top upper goru ,Top B sand and Top C sand from early cretaceous, faults are also marked .Time
contour maps were generated after that some sections were converted into depth section with the
help of average velocity and finally depth contour maps were generated ,that helped to know the
basic mechanism of the tectonic movement in the area.
The major faults in the area are normal faults because the study area is located in
transtensional regime. There may be some reverse faults due to some local activity.
