Geotomo GeoThrust 6.4 Linux

Geotomo softwares: Tomoplus , Vecon , Geothrust

• GeoThrust has been designed with a workflow architecture to obtain an accurate earth model and earth image in time and in depth from data recorded with irregular geometry in areas with rough topography, complex near-surface, and complex subsurface, with uncompromisingly high technical specifications for data analysis and quality control, but easy to learn and easy to use.DISTINCTIVELY UNIQUE FEATURES
  • The near-surface model is estimated by nonlinear tomography applied to first-arrival times that accounts for topography and resolves lateral and vertical velocity variations.
  • Aside from statics corrections, the corrections for the near-surface are performed by wavefield datuming — an essential requirement for imaging from irregular topography.
  • GeoThrust performs subsurface velocity estimation, modeling and imaging from topography, not from a flat datum, based on rms and interval velocities estimated at reflector positions, not at reflection positions.
  • The system provides the analyst with powerful interactive tools to perform quality control of geometry and for appropriate specification of signal processing parameters, and image-based picking rms and interval velocities using four different strategies.
  • The system is based on a workflow architecture that manages the project for the analyst and allows the analyst to focus on the geological and geophysical aspects of the project.
