TITLE:

A comparison Study of Target-Oriented Full Waveform Inversion Methods: PGF and RPGF

KEY WORDS:

Full Waveform Inversion, Target oriented FWI, PGF, RPGF.

SUMMARY:

This study aims to investigate the application of two distinct target-oriented Full Waveform Inversion (FWI) techniques: Patched Green Functions (PGF) and Recursive Patched Green Functions (RPGF), using two different finite-difference schemes for the discretization of the Helmholtz equation: the conventional fourth-order scheme and the 9-point mixed scheme. The study evaluates the optimal combination of these methods to provide a high-quality model image with an optimized execution time. The target-oriented FWI techniques, PGF and RPGF, are applied to the Marmousi dataset, a benchmark in seismic inversion research. The results highlight the faster execution speed and lower computational demand of the target-oriented FWI methods compared to the conventional technique, detailing the inversion time variations inside and outside the target areas for the PGF and RPGF methods, respectively.
