2D i-stats Workflow for Image Based Near Surface Modeling for Statics Corrections
The i-stats workflow provides an image-based equivalent-medium near-surface model for statics corrections. It does not require first-break picking as for traveltime tomography, does not require source wavelet estimation as for waveform inversion, does not fail velocity inversions as in traveltime tomography, does not suffer from velocity-depth ambiguity, does not require data modeling (traveltime or wave field) as for any inversion method, and does not exhaust computational resources as in waveform and joint inversions.
