Establishing the Gap Between Manually Picked and the Predicted Seismic Velocity

Abstract

In exploration seismic, the seismic velocity is the key to delineating many physical properties of the subsurface. There are ways to calculate the velocity and, most popularly, it is picked manually for any seismic project. The velocity picking method has a few limitations when it comes to its quality, time consumption in this process, and the money spent during the whole work. The main objective of this paper is to provide velocity estimation of the respective region (three-dimensional seismic) derived from the velocity field available in the region from a few 2D seismic lines. The purpose is to avoid manual velocity picking errors and make the overall velocity in the region more geologically consistent with the surrounding data. Even more importantly, a seismic velocity volume assessment model created through this technique can also support any future 3D seismic imaging.
