Refraction Statics via Tomostatics
Tomostatics entails deriving a near surface velocity model via turning ray tomography, then computing the associated static corrections.
The output velocity (actually slowness) model is parameterized on a 2D or 3D grid (i.e., rather than via a series of discrete layers as in the GLI case), and experience has shown that it can produce a better statics solution than that obtained by the GLI algorithm in cases where the near-surface geology departs significantly from layer-cake. TGS uses the industry-leading GeoTomo 3rd party software for its 2D and 3D
