2D seismic interpretation using seismic and well log of Badin area, lower Indus basin, Pakistan (P-1100) (MFN 3922)

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.
