Seismic velocity model building: CE in Dallas, 2 November

Abstract

Depth conversion and depth imaging (depth migration) of 3-D seismic data require a geologically and geophysically competent velocity model. The constantly improving quality of seismic data and increasing survey accuracy demand a correspondingly high quality and accuracy standard for velocity models. In depth conversion of time-based maps, for example, using a single regional velocity function is rapidly being replaced by depth conversion of both the interpreted surfaces and the seismic data using a single unified high quality 3-D velocity model.
