Quantifying the Incremental Value of XRF Elemental Data for Well-Log-Based TOC Prediction: A Fusion Strategy Evaluated Under Strict Cross-Validation

Total organic carbon (TOC) is a key parameter for source-rock evaluation, but laboratory measurements are sparse and do not resolve continuous vertical variation. Conventional well logs provide continuous physical responses, whereas X-ray fluorescence (XRF) data add geochemical i...
