Structural & Stratigraphic Interpretation of Migrated Seismic Sections of Fortabbas Area, Punjab Platform, Pakistan

Punjab Platform in Pakistan covers an area of 70,000 sq. km, lies at the edge of Pakistan India political boundary, which is sparsely explored for petroleum research. Punjab Platform is a westward dipping gentle monocline containing Paleozoic to Paleogene sediments overlain by Neogene fluviatile deposits. In this study we used five migrated seismic stacks with three strike lines and two dip lines acquired by OGDCL in the study area close to Fort Abbas well#1 and wire line logs of same well. By using wire line logs synthetic seismogram is developed and correlated with seismic data for picking reflectors of Khewra Sandstone, Nammal & Patala formations on available seismic sections. Time and depth contour maps are constructed by using Surfer software to highlight the subsurface structural trends. Normal fault of minimum throw is also picked up on seismic section and mapped by using Surfer software. An anticlinal structure at Cambrian level is observed on structural contour maps of the study area. A detail seismic stratigraphic study is done to highlight the stratigraphic trend in the study area but the results indicate that there is no prominent stratigraphic trap since a sigmoidal seismic facies is interpreted on seismic sections.
