Abstract:
The mining industry is increasingly using 3D seismic reflection datasets, from project genesis through to mature mine sites. During processing of the reflection data, the refracted arrival is digitised and used to correct for near-surface velocity variations. By performing a 3D inversion of these first arrivals, a high-resolution, tomographic velocity model can be obtained that provides additional information in the top portion of the seismic volume.
