Structural & Lithostratigraphic Interpretation of Seismic Profiles in Badin Area (P-1572) (MFN 2858)

Abstract

Badin area is a classic example of extensional tectonics represented by Horst & Graben geometries. In order to carry out the structural and stratigraphic interpretation of the Badin area, three seismic dip lines of 31.87 km, 31.04 km, 20.58 km and one strike line of 7.36 km were interpreted. Two way time and depth mapping helped in delineating the structural trend and understanding the tectonics of the area. Subsurface mapping reveals that major fault trend is NNW-SSE. Tectonic activity continued throughout the deposition of Chiltan- Upper Goru level. There are indications of reactivation of faults indicating the occurrence of various tectonic episodes. Existing structural trend of the area provides basic components of a profile petroleum system. Grabens are supposed to be the kitchen area of hydrocarbon generation while the faults have provided migration pathways to facilitate hydrocarbon migration from source to reservoir. Faults are also helping in the formation of hydrocarbon traps. The main constituents of petroleum system are present, proven by a number of oil and gas discoveries but there is still a requirement of advance techniques to improve seismic resolution and quality of interpretation.
