Anisotropic VSP reverse-time migration with optimal pure aeoustic wave and complex wavefield separation

Ignoring anisotropy characteristic of subsurface media may lead to misplaced images and low resolution of the target for the reverse-time migration (RTM). The mature anisotropic RTM methods are mainly based on the pseudoacoustic wave approximation. Although these schemes have high computational effi...
