Pre-stack depth migration will generate common image point gathers (CIPG). Residual velocity errors are scanned for tomographic inversion. For given common image point gathers (CIPG),ray tracing computes path lengths of cells along the ray and residual time errors are used as data for tomographic inversion. Skeletons were generated replacing horizons.

In-line and cross-line dips were estimated. Ray tracing and inversion solves
for velocity update. Workflow architecture allow users to concentrate geological
aspects. Quality control routines are key for the success of tomography.

Demigration and parsimonious migration loop make iteration efficient.
Anisotropy analysis allows to incorporate well tying and imaging. A turn
key solution with
proper hardware can solve tomography more effectively.
