Abstract:
This dissertation presents the 2D seismic interpretation of Badin area in Lower
Indus basin, which is located in the southwestern periphery of the Indian plate. The
key objective of this project is to delineate the subsurface geometry with the help of
different seismic techniques in order to understand the petroleum system of the
concerned area. Main emphasize is on the interpretation methodology adopted in
order to illustrate the horizons and faults. Beside this time and depth contour maps are
generated along with petrophysical analysis and reserve estimation. As the study area
tectonically present in extensional regime, accordingly dominated by horst and graben
structures. Grabens are of immense exploratory importance as it believed to be the
kitchen area of hydrocarbon generation, whereas the faults are important in different
aspects, of which the foremost is trap formation and further it facilitate in
hydrocarbon migration from source to reservoir. Study area holds all the major
elements of petroleum system verified by a number of oil and gas discoveries;
however some seismic reflectors were not distinctive. It was realized that to interpret
these horizons and to improve seismic resolution, a denser seismic grid most likely
3D seismic is required. Thus, interpretation of these horizons should be left for future
study.
