GRAPHIC SCIENCE GEODEPTH INVERSION BACKGROUND AND DESCRIPTION

The main goal of seismic interpretation is to estimate subsurface model parameters and to obtain a detiled Image of the subsurface structure. The most common methods used for producing depth images from stacked time data were based on Dix'formula (1955), converting stacking velocities to interval velocities. However, these methods do not take into account the complexity of the time-to-depth conversion problem. More accurate depth images can be achieved by applying comprehensive seismic inversion methods such as the one implemented in the Graphic Science GeoDepth software package.
