3D-Kinematic Modelling and Hydrocarbon Potential of the Gurguri Block, Kohat Fold and Thrust Belt, Pakistan Using MOVE

Umer Habib, Ahsan Naseer, Bilal Hussain

The Gurguri block represents the foreland fold and thrust belt at the southern margin of Himalayan orogen, Pakistan. This research is a part of exploration study carried out to discover new oil and gas resources under highly deformed Gurguri block structures. The study area is strongly buckled and is outlined by thrust faults and folds due to north-south compressional stresses devised from the later northward movement of Indian Plate. This study comprises acquired two-dimensional data surface data integrated into an internally logical 3-D workflow in move suit 2013.1.0, which was then easy to assimilate and attain beyond known points to validate structural constraints within the area. The rocks exposed in the Gurguri area, are relatively more ductile and deformed into, tight, doubly plunging, overturned, and inwardly faulted E-W trending anticlines interceded by broad synclines and underlain by a thick sequence of Panoba shales of Eocene age. The 3D model suggests the study area is dominantly, a southverging structural system propagating southward. Overall, the displacement along the thrust fault is up to 850 meters and the percent shortage calculated in the area is up to 60%.
