Accuracy rate in task estimation, ensuring projects are delivered on time, as per velocity reports. SeisImager2D refraction software is a fully integrated refraction modelling and interpretation software package that runs on your Geometrics seismograph or PC. If you uncheck the “Change”, all traces are shown black.
Most commercial application require SeisImager2D to be upgrading to the standard Licence which supports up to 16K samples per trace, 128 traces per shot, 360 traces per interpretation, and 65 shots per interpretation. This is by far the most common supplied processing package for refraction analyses. Supplied free with all Geometrics seismograph purchases the lite version permits up to 16K samples per trace, 64 traces per shot, 51 traces per interpretation, and 12 shots per interpretation. Before you commence ray tracing navigate to Velocity model/Extend velocity model to remote sources. Make sure the beginning the end distance is sufficient to include the offend shots.
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. Choose from three methods of analysis to best suit the geologic conditions. Take a quick look with a 2 or 3-layer time-term analysis.
The velocity model will then be extended to include the offend shots. Make sure there is no time difference among shots. Make sure there is no time difference between shots. If you want to change the color of traces depending on files, change component (2 to 10), check “Change” and click “OK”.
If you prefer traditional methods, picwin 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".
