XW Tomo
Crosswell Tomography
Efficiently derive velocity structures among vertical or deviated wells with fast and robust ray tracing

Data input
- Import all records at one time
- Efficiently assign geometry with layout chart
- Support more than two vertical or deviated wells
- Optionally load first-break picks together with seismic data for reprocessing
- Support most third-party picks formats

Data processing
- AGC, trace balance, and frequency filtering
- Trigger delay correction
- Undo or redo multiple steps in data processing
First-break picking
- Manually pick first breaks with a trace magnifier
- Automatically pick first breaks guided by velocity or waveform phase
- Overlay shear waves of opposite polarity to assist picking

Tomography
- Automatic initial model building based on first arrivals
- Fast shortest path ray tracing
- Regularized tomographic inversion with multiple constraints
- Update the display of first arrivals and ray paths in real time
- Display the picked and calculated first arrivals on seismic traces
- Interactively pause and resume or stop the tomography procedure
- Review results of each iteration with fitting error analysis
- Export velocity section with a blanking file
Plotting
- Display velocity sections with colours, contours, and editable lithologic symbols
- Overlay velocity section with ray paths
- Trim velocity section based on ray paths
- Plot well data
