Abstract: Oil and gas production forecast is a critical technical approach for optimizing development strategy and enhancing recovery factor of oil and gas fields. The theoretical system of oil and gas production decline has systematically been reviewed, and a comparative evaluation between conventional empirical models and analytical methods has been conducted in terms of their theoretical foundations, applicability, and limitations. In addition, innovative application of machine learning in production forecast of complex reservoirs has been discussed in detail. The analysis results show that: (1) Traditional methods show robustness for conventional reservoirs but exhibit constrained application performance in unconventional oil and gas reservoirs due to strong heterogeneity and nonlinear multiphase flow; (2) The data-driven models demonstrate superior prediction performance for unconventional reservoirs through automated feature extraction and spatiotemporal correlation modeling; (3) The physical-informed hybrid models effectively integrate data-driven advantages with physical mechanisms, delivering enhanced reliability in complex conditions and long-term production forecast. The study concludes that artificial intelligence significantly improves prediction accuracy and reliability in oil and gas production forecast, with machine learning and deep learning offering novel technical support for complex reservoir development. However, challenges persist in engineering applications, particularly in real-time computation and model interpretability, where further interdisciplinary research is needed on artificial intelligence and oil and gas domain to promote intelligent and high-quality development of the oil and gas industry.
