Geogiga DW Tomo 1.0 - Refraction Tomography SoftwareNew

Features | Screenshots

Refraction Tomography does not require layer assignment and phantom prior to inversion. The complex velocity structure can be estimated directly from the first arrivals. This approach is especially suitable to derive the structure with no distinct layer interface due to the gradual velocity change where the traditional interpretation methods are invalid.

Geogiga DW Tomo utilizes the robust ray tracing and regularized inversion approach; allows the variable surface. The estimated model can also be used for the statics correction in seismic reflection data processing.

Main Features:

• Load all shots along a line at once
• Quickly check and modify geometry
• Band-pass filter and gain control with multiple options
• Undo/Redo multi-step operations on seismic data
• Interactively pick the first break
• Robust ray tracing
• Regularized iterative inversion with constraints
• Use multiple approaches to build initial model
• Allow variable surface
• QC the picked and calculated first arrivals directly on the seismic traces
• Fitting error analysis
• Interactively pause or resume the procedure during tomography
• Update the display of first break and ray path in realtime
• Review the inversed model of each iteration
• Output color section overlayed with ray path
