Abstract:
To develop an understanding of structural analysis, already interpreted seismic
lines were re-interpreted in correlation with well data for the confirmation of seismic
structural interpretation of Badin area, Lower Indus Basin. Directorate General of
Petroleum Concession (DGPC) provided 2D seismic reflection data required for
conducting this research.
Structural analysis revealed the trend of deformation through time and trapping
mechanism that has been proven prospective. Leads other than the prospect zone were
also marked. All the faults have emerged from Chiltan limestone. The younger faults in
assistance have helped making Horst-type structural traps. Due to poor data quality some
of the faults could not be marked to the depth of Chiltan limestone.
Three horizons have been marked, as all the faults are originated from Chiltan and
terminate below or at Khadro because Khadro is basaltic. These two reflectors have been
marked to understand the structural geometry. Top Lower Goru is reservoir in this area so
it is also marked to understand the already producing well’s geometry.
