Seismic imaging in thrust-belt environments like the foothills of the Himalayas benefits significantly from interpretive input to velocities used for time and depth migration. With low fold in the near surface, low signal-to- noise ratios on the image gathers, ...

In a tectonically complex area of northwest Pakistan, MOL Pakistan and its partners acquired two 3D seismic surveys. Extreme topography led to irregular shooting geometry. Varied surface access over this terrain required a mix of Vibroseis and dynamite source ...
