Simultaneous Surface Consistent Phase & Static Compensation

Surface-consistent short-wavelength statics and phase-correction module technique

It is industry standard to apply a correction to the statics problem arising from near-surface conditions.

However, phase is not compensated for, even though the near-surface affects both statics and phase. The module SCPHAT estimates shot and receiver-consistent statics and phase by maximizing the stack power. It is an extension of the surface-consistent residual statics approach proposed by Ronen and Claerbout in 1985 (Geophysics, Vol. 50, No. 12). Improved continuity of events over traditional approaches can be achieved when phase and statics distortions of the near-surface are accounted for.
