Abstract

Depth velocity modeling is a non-unique problem in Seismic. There are uncertainties in both velocity and structure depth. To reduce uncertainty in the velocity model, an integrated study of processing, interpretation and modeling is performed. 

The goal of this presentation is to demonstrate the workflow for obtaining a high-resolution, structurally constrained velocity model that satisfies both seismic and well data.  Horizon and fault interpretation is performed in SeisEarth.  The results are sent to the SKUA-GOCAD modeling application to create a geologically consistent structural framework and propagate velocity attributes.  SKUA-GOCAD modeling helps reduce uncertainty in the structural model. A SKUA generated velocity model is further updated using tomography workflows to obtain a high-resolution, well calibrated, structurally constrained seismic velocity model.
