Seismic Imaging in the Foothills of the Zagros Mountains Using Geologic Constraints

R. Vestrum1

1Thrust Belt Imaging


Seismic imaging in thrust-belt environments like the foothills of the Zagros 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, and complex horizon geometries, automated velocity-model-building tools fail to produce an optimum velocity model for TTI anisotropic depth imaging in these areas. In a setting with such under-constrained seismic velocities, geologic constraints are crucial in the interpretation of our velocity model.
