Improving Business Decisions by Evaluating Subsalt Structural Uncertainty and Illumination with Modeling and Re-migration

Building a salt velocity model is usually an iterative process. Based on seismic character alone there is often a large range of alternative salt models. The iterations can often take on the form of trial-and-error in trying to understand the geologically most likely model. We present a solution to allow integration of geological insight in the velocity model building. The solution consists of a seamless system of flexible model editing and fast migrations. This creates an arena for the geophysicist and the geologist to work together. The crucial component is the interactivity, or the ability to work in the same time frame. This means that several salt models can be created and resulting images analyzed during the course of a working day.
