Abstract
This study investigates the impact of amplitude anomalies caused by heterogeneities in the near-surface layer on the accuracy of acoustic inversion results. The analysis is based on both synthetic data, generated via finite-difference modeling, and real seismic data. Inversion results demonstrate improved accuracy and stability after applying surfaceconsistent amplitude correction procedures. The study also investigates the reliability of models derived from seismic inversion under the influence of near-surface heterogeneity. The findings highlight the importance of evaluating the reliability of inversion-derived models when near-surface effects are present.
