Analysis of subsurface structural trend and stratigraphic architecture using 2D seismic data: a case study from Bannu Basin, Pakistan

Abstract The present study is focused on the subsurface geology of Bannu Basin, a part western Indus foreland Pakistan. For this purpose, some regional seismic profiles and deep exploratory wells data have been used in integration.A total ten mappabale reflection events identifed which are representative specific geological units. In general, based formation trends, horizons dipping northwest direction area. area generally deepens toward due to sediments load northwest. profile MWI-83 shows unique faults bounded anticlinal structure that has also mapped two-dimmensional contour maps. This could be regarded as potential hydrocarbon entrapment. contoured for entire grid both time depth domain obtain clearer image individual stratigraphic 2D maps Lower Permian aged Warcha Sandstone, Middle Triassic Tredian Formation Early Jurrasic Datta prepared using gridded TWT profiles. show four way clouser oriented southeast dierction. closure was computed 24 Sq km approximately. Furthermore, tops five correlate understanding lateral vertical variations layers. correlation Formation’s thickness increases at centre basin whereas decreases east south flanks basin. Reasons Wells failure were concluded basis final well report these occur poor quality mechanical problems. Reservoircharacterization statistical rock physics petrophysics coupled with core analysis can provide further insights into exploration.
