A Residual Feature-Gated BiGRU Framework for Blind-Well Lithology Identification from Well-Log Data
Lithology identification supports reservoir characterization and well-log interpretation. Random sample splits can overestimate performance because adjacent samples from the same well are correlated, while logging-channel differences may be underused. We propose a Residual Feature-Gated BiGRU framework (RFG-BiGRU) for...
