Prediction of Fault and Fracture Density From Seismic Attributes and Machine Learning Models Calibrated With Borehole Image Logs

Basin Research, Volume 38, Issue 3, May–June 2026.
This study integrates post‐stack seismic attributes with a CNN‐based workflow to characterize sub‐seismic deformation in shale gas reservoirs. A near‐linear correlation is established between seismic characterization methods and borehole deformation counts.
