- Make sure the beginning the end distance is sufficient to include the offend shots.
- Take a quick look with a 2 or 3-layer time-term analysis.
- This is by far the most common supplied processing package for refraction analyses.
- Make sure there is no time difference between shots.
- Choose from three methods of analysis to best suit the geologic conditions.
- If the maximum traces is smaller than the total number of traces, increase the maximum traces, check “Change dimension size” and click “OK” to change dimension size.

If you prefer traditional methods, use the delay-time (reciprocal) method and view the process step-by-step. If you expect lateral velocity variations, use the optimised tomographic analysis that runs quickly and accurately. Make sure your dimension size is large enough. To start, select “option”, then “Dimension size”.SeisImager2D Pro
- Accuracy rate in task estimation, ensuring projects are delivered on time, as per velocity reports.
- If you prefer traditional methods, use the delay-time (reciprocal) method and view the process step-by-step.
- If you uncheck the “Change”, all traces are shown black.
- To start, select “option”, then “Dimension size”.
- Make sure your dimension size is large enough.
- If you want to change the color of traces depending on files, change component (2 to 10), check “Change” and click “OK”.
- Before you commence ray tracing navigate to Velocity model/Extend velocity model to remote sources.
