Prestack wave-equation depth migration in VTI media

摘要

Wave-equation prestack depth migration (PSDM) naturally handles multi-arrivals, is not limited by the high frequency assumption of Kirchhoff-based PSDM and can, therefore, produce higher quality images in areas of complex geology. In addition, it has been shown that anisotropy, commonly encountered in petroleum exploration, affects image focusing and positioning. Therefore incorporating anisotropy in wave equation PSDM will produce a superior image!
