Velocity Modeling

Tsunami Development utilizes INTViewer and its Java-based plugin API to create tools for building and updating the velocity models used in its leading-edge seismic migration and imaging solutions.

Challenge

Tsunami Development is known for the quality of their pre-stack imaging software, but even the best migration solutions depend on good velocity models that include time and depth as well as the additional modeling needed for anisotropic migrations. Working with customers, Tsunami developed workflows that allow users to quickly and accurately build the models they need. However, these workflows required the use of multiple software packages and involved the associated problems of moving data between them. Tsunami wanted to develop a single, easy-to-use solution for these tasks. An effective solution required extensive visualization and data I/O capabilities, in addition to being able to manipulate and interact with the models themselves. Creating and supporting all this functionality required significant development resources that would detract from Tsunami’s primary focus on imaging.

INT Solution

Tsunami was already familiar with INTViewer, having used it for many years as a tool to support their migrations. When testing for the optimal imaging parameters, INTViewer proved to be the fastest and easiest way to review analysis results: yielding better seismic imaging and helping to eliminate costly re-reruns. By taking advantage of INTViewer’s standards-based plugin framework based upon the Oracle^® Netbeans Java Rich-client-platform, Tsunami could leverage INTViewer’s functionality and concentrate on developing model building plugins to support its migrations. Tsunami chose to concentrate on the geophysical details of model building, and let INTViewer handle the rest.

With its latest software release, Tsunami shipped twenty INTViewer plugins, and more are under development. Tsunami’s plugins allow clients to create, modify and QC their models in a single integrated tool. For time processing, both velocity and eta models can be created. For depth processing, models for VTI and TTI migrations are supported. Additional models that tie well data to depth migrations are also provided.
