MORK™—Anisotropic Phase Screen Module
MORK provides one way wavefield propagation for both migration and demigration using a dual-domain phase screen approach. It can be applied in the shot-profile, common-azimuth, or common offset domain as either a migration or as a de-migration. The methodology enables you to test various velocity alternatives and make significant velocity modeling changes prior to applying more computationally intensive methods. Key features include
- isotropic, VTI, and TTI migration and de-migration;
- migration from topography in shot-profile mode;
- steep dip imaging;
- extreme wave equation migration speed—for example, 16 km cubes at 500 shots per hour;
- is parameterized using Thomsen notation: ε, δ, VNMO, φ, and θ.
