Abstract

The proven hydrocarbon discoveries in the periphery of Mizoram state in the north eastern part of India impelled Oil India Limited (OIL), Duliajan to start the hydrocarbon exploration in the area. The area is extremely difficult with hilly terrain, drastic elevation variations having geological setting with thrusted and folded beds. The seismic data acquisition is a great challenge in such kind of highly undulating terrain with complex subsurface. OIL has acquired more than 1300 Ground Line Kilometers (GLKM) 2D quality seismic data. The paper explains about the details of challenges faced, mythology & strategies adopted by OIL for acquisition of the quality seismic data and its correlation and integration withall other geoscientific data like geological, geochemical, gravity and magnetic for understanding the subsurface model for successful hydrocarbon exploration
