Geophysics as a tool for mapping of subsurface geological features- Introduction. Gravity and magnetism measurement methods. Gravity anomalies and their measurements. Magnetics anomalies and their measurement. Seismic methods.

UNIT II

Wave theory, seismic wave reflection and refraction and their use in data acquisition. Seismic attributes- Introduction. Classification of attributes, Reservoir properties, tectonics and fault planes. Lithology, structure and Sedimentalogy.

UNIT III

Land and marine geophysical methods. 2D 3D seismic methods. 3D exploration. Non conventional methods, VSP, shear waves and channel waves, seismic data processing, attribute analysis and migration techniques.

UNIT IV

3D interpretation- fault recognition and mapping. Limitations on 2D fault mapping. Advantage of 3D diagram. 3D structural mapping. Stratigraphic interpretation. Analysis of direct hydrocarbon indicators.

UNIT V
