... and Luo, 2004). For refraction methods, the accuracy of the refraction static correction largely depends on the quality of the first arrival traveltimes. However, seismic amplitudes at far offsets are often too weak to pick. To overcome this problem, the theory of Super-Virtual Interferometry (SVI) is...

In the previous processing of this project, long period refraction static corrections and short period surface consistent static corrections were applied in the time domain prior to migration. Traditional refraction statics solutions address the time delays caused by shallow velocity...
