EFit
Interactive Event Fitting
Interactively determine velocity and thickness of a layered model by fitting T-X curves with refraction and reflection events
Data input
- Load single or multiple records
- Check and assign geometry
- Optionally load velocity model for reprocessing
Data processing
- AGC, trace balance, and time-variant scaling
- Frequency filtering
- Trigger delay correction
- Undo or redo multiple steps in data processing
Event fitting
- Define initial velocity model
- Calculate T-X curves of reflected and refracted waves
- Plot T-X curves on seismic records
- Interactively adjust velocity model to fit T-X curves with reflection and refraction events
- Output velocity model
