Surface Consistent Phase & Static Correction
Near-surface conditions can strongly perturb seismic signals on land data so TGS has a full suite of tools to compensate for surface-consistent variations in wavelets, amplitudes and statics. Residual surface-consistent variations in phase do not always receive attention, but TGS has an effective module, SCPHAT, that simultaneously determines shot and receiver-consistent phase and statics by maximizing stack-power. Improved continuity of events can be achieved when phase and statics distortions due to the near-surface are accounted for, as illustrated in the following CDP stack example.
