WebZhang et al. (2024) proposed a time-lag FWI (TLFWI) which uses a time-lag cost function (Luo and Schuster, 1991; Chavent et al., 1994) to reduce amplitude errors in the standard data-mismatch cost function (Tarantola, 1984). Wang et al. (2024) further applied TLFWI to velocity model building for areas with the presence of salt bodies. Webwave penetration.After that, TLFWI. was carried out to update the model and capture velocity anomalies from shallow to deep, using both refraction and reflection energy. The final 24 Hz TLFWI achieved a high-resolution velocity model and improved seismic images. The karsts and collapse features in a shallow limestone formation were well resolved,
