A raypath-consistent receiver correction in PS converted wave processing through seismic interferometry: New application for tropical zones: New application for tropical zones

The estimation of static corrections is an issue still unsolved for PS converted wave processing. Due to the PS converted wave usually arriving at the surface at non-zero angles, the surface consistent approach is no longer valid, and corrections become non-stationary, i.e. the correction is not sta...
