Randomized trial demonstrates improved imaging of near-wellbore geology, suggesting enhanced oil and gas resource discovery.

The aim is to enhance acoustic reflection imaging logging by optimizing the use of diffracted energy for better geological imaging.
Introduced a diffraction-optimized stacking method based on diffraction theory and Huygens’ principle.
Applied a travel-time correction operator to improve signal-to-noise ratio during stacking.
Validated the method on synthetic datasets to increase stacking fold and enhance image quality.
Achieved over threefold increase in stacking fold with improved signal-to-noise ratio.
Enhanced structural delineation in complex reservoirs of the Sichuan Basin.
Improved event continuity of key layers for better reservoir characterization.
