Dynamic Adaptive Fusion Model (DAFM) for Real-Time Oil Production Forecasting

This study proposes the Dynamic Adaptive Fusion Model (DAFM), a real-time intelligent forecasting system that dynamically integrates Decision Trees, Random Forests, XGBoost, and BiLSTM networks via adaptive gating mechanisms to overcome the limitations of static models, achieving superior accuracy (R² = 0.97) and rapid inference for oil production prediction.
