Kirchhoff Prestack Depth and Time Migration
The most widely used migration algorithm in the industry
Accommodate a range of geological settings and acquisition geometries with flexible, amplitude-preserving implementation.
Interactive velocity analysis (InVA) provides a full-featured interactive velocity analysis package for time-domain projects of any size. Our InVA solution includes
The latest version offers an updated traveltime generator to enable full ray-traced anisotropic moveout correction of gather displays. This provides consistency between moveout corrections in InVA and our proprietary Kirchhoff prestack time migration.
InVA also incorporates the ability to define spatially variant stacking mutes while picking velocities. This capability coupled with the high-order dual-parameter velocity picking and fully ray-traced anisotropic moveout means that a more precise spatially variant mute can be defined both quickly and easily.
