Our Solutions

Elastic cutting-edge solutions for seismic depth imaging and velocity model building.

All of our algorithms make use of the two-way elastic wave equation, which intrinsically include anisotropy and all reflections and conversions of P-waves and S-waves.

Our visco-elastic reverse time migration solution allows for accurate imaging in the presence of strong velocity contrasts causing complex wave paths. It also allows for the output of various imaging conditions to provide the geophysicists with additional information.

Our velocity model building algorithms are highly complementary to each other, because they are all based on the two-way elastic wave equation. The automated velocity model building tool rapidly builds a smooth velocity model from a simple starting model, or it updates the velocity model below high velocity layers. Our elastic full waveform inversion updates the smooth velocity model with fine details providing the smooth icing on the cake.

All of our solutions are integrated into a user-friendly interface, with graphical representation of workflows, and the job submission and the control tool.
