Abstract
Prestack depth migration algorithms based on one-way wave equation extrapolation have been widely used in the oil and gas industry in recent years, especially in areas with complex salt structures. The methods are known to be amplitude friendly and can produce high-quality images, especially when triplication encountered in areas with complex salt structures where Kirchhoff migration becomes inadequate. Here, we implemented and applied the phase-shift-plus-interpolation (PSPI) method for imaging synthetic and marine field data.
