High-resolution seismic time-strain estimation

SUMMARY

This study introduces and evaluates two seismic time-strain inversion methods: total variation (TV) regularised inversion, and joint inversion with segmentation (JIS).

Both methods effectively recover seismic time-strain while suppressing noise. Synthetic data experiments highlight the superior performance of JIS, which provides cleaner, more accurate estimates and segments strain into userdefined classes, enhancing interpretability and offering an indirect measure of uncertainty.

Using a warm start, JIS achieves faster convergence and improved computational efficiency.

These methods represent a robust framework for high-resolution, interpretable seismic analysis, with future work focusing on extending them to 3D field data for broader validation and scalability.
