Abstract
The 2005 Tanami Seismic Survey consisted of 720 km of deep crustal seismic reflection data acquired along 4 lines. The processing was aimed at obtaining a high quality image of the crust from the Moho to the surface, with particular emphasis on imaging shallow features and steeply dipping reflectors. The key processing steps applied here included refraction and automatic statics, spectral equalisation, detailed velocity analysis pre and post DMO, and omega-x migration. Near surface features were better imaged using a floating datum technique for refraction statics application, with only the residual CDP static applied before NMO correction, and the mean CDP static after migration. Offset regularization of CDP gathers pre DMO employed trace interpolation based on dip coherency which had the dual advantage of improving signal to noise, and normalizing amplitudes in low-fold areas, thus reducing migration smiles.
