ThrustLine is a unique 2-D surface seismic data analysis system developed by GeoTomo.  Drs. Oz Yilmaz and Jie Zhang designed and supervised the development of the software package.  ThrustLine combines advanced near-surface imaging techniques with innovative subsurface imaging strategies, and presents a powerful solution to difficult earth imaging problems.  It is particularly applicable to areas with complex structures associated with overthrust tectonics and complex near-surface with irregular topography.

The program provides a workflow that starts with picking the first-arrivals and performing nonlinear near-surface tomography.  Wave-equation datuming is then applied to reference the prestack data from the irregular topography to a flat datum using the near-surface tomographic solution.  Next, the program offers a unique approach for building an RMS velocity field associated with events in their migrated positions.  Picking RMS velocities for complex structures such as those associated with overthrust tectonics after migration rather than before migration is essential for the subsequent earth modeling in depth.  Based on the resulting RMS velocity field, the workflow continues with earth modeling and imaging in depth - all using advanced wave-equation imaging algorithms.  The final deliverables - RMS velocity field, velocity-depth model, prestack time and depth migrations, demigration, poststack depth migration, and project history, are all well organized by the program, and any of these can be displayed by a single mouse click.

ThrustLine is designed for Windows, Linux Workstation, and Linux Clusters.  For any evaluation request, please contact: support@geotomo.com
