Ray-based tomographic model for more accurate picks in complex residual moveouts

An accurate velocity model is paramount to generating reliable subsurface images, particularly in complex geologies where exploration risk and drilling costs are high.  ION’s General Moveout Tomography, or GMO, offers a non-parametric auto picking algorithm for residual moveout correction which produces more accurate picks. Using this method, the velocity model is fine-tuned where channels cause small-scale velocity anomalies or where salt causes sharp lateral velocity variations.  ION’s GMO tool produces more accurate and higher resolution tomographic velocity updates, and leads to faster convergence with fewer iterations.
