Geometry and Refraction Statics
At the onset of a project, we examine all imported survey information
for completeness. Based on the “recording patch”
definitions provided with the field data, we assign source and
receiver station location coordinates to the seismic traces for
each source record in the survey. We meticulously verify the actual
x, y, z locations—particularly source locations—to avoid
any of the discrepancies that often occur due to cultural obstacles
in the field.
Break Picking and Refraction Statics
Geotrace uses proprietary as well as industry-leading third-party software for first break conditioning and picking. Once the critical step is completed, refraction analysis may proceed. This is truly a near surface modeling exercise, and the answer is in the breaks.
Geotrace employs both Hampson-Russell GLI3D and Renegade Seismic
Studio software packages for generalized linear inversion and
delay-time refraction solutions, respectively. Challenging datasets
often require empirical model perturbations in both approaches
to arrive at the optimal solution.
