FGS has developed imaging capabilities of 3D turning-ray tomography, tomostatics, reflection tomography, full-waveform inversion (FWI) and forward modeling from topography. We have also developed proprietary imaging software using both refraction and reflection seismic data for velocity model building, prestack depth imaging and geopressure prediction. 

3D High-Resolution Tomostatics

• Nonlinear (Independent of Initial Models) 
• Constrained Inversion (if Well Logs Available) 
• Parallel Computing (OpenMP, MPI)
• Applicable to Large 3D Surveys (> 10,000 km²) 
• Efficient & Robust First-Arrival Picking
