Abstract
An interactive method has been developed for carrying out seismic velocity analysis that results in a three dimensionally tied and consistent velocity field for either stacking or time migrating 3-D seismic data (also grids of 2-D data). This method uses interactive horizon-based velocity picking and statistical data fitting as the primary model building tools. The motivation for this development comes from difficulties we experience in picking seismic velocities from data which is either poor in its signal to noise ratio characteristics or is structurally complex and requires complicated velocities to image the subsurface.
