Refraction Shooting
There are a number of programs for refraction surveys.
- BRED (7.0.1 ) apply linear or hyperbolic correction in time to traces. This sometimes makes picking first breaks easier. It can also be used in flattening reflections for a totally different type of problem. See section 7.0.1 for more.
- PICRESTORE (8.4.1 ) Restore segpic.m picks on data reduced by BRED. 6.0.12
- BPIC (8.4.3 ) automatic first break picker, or inserts picks from a file (segpic.m 6.0.12 or suxpicker SU program).
- BSHF (12.1.1 ) static shift by header pics to QC picks.
- BDAT (8.4.5) datuming program for refraction data (adjusts data to the shot elevation using an overburden velocity)
- BREF (8.4.6 ) Direct wave (8.4.6.1), and Refraction (8.4.6.3) analysis setup.
- OCTAVE DELAYTM (8.4.6.3) delay time solution.
- OCTAVE DELAYTMR (8.4.6.4 ) reciprocal delay time solution (cross-river shooting).
