Abstract: Objective Under the "dual carbon" goals, the high energy consumption and emissions of traditional oil and gas field energy supply models urgently require solutions, yet systematic reviews and analyses of green energy applications in these contexts remain limited. Methods To assess the application of green energy in oil and gas fields and develop scientifically tailored energy supply strategies, a methodology combining literature review, case studies, and technical adaptability evaluation was employed to systematically analyze global research on green energy applications in oil and gas fields, integrating industry reports and practical cases. The focus was on the application status and limitations of solar energy, geothermal energy, waste heat, wind energy, and wave energy. Results Findings indicate that these green energy sources are feasible for oil and gas fields, with most technologies already implemented but possessing further development potential. Photovoltaic technology is relatively mature but constrained by regional conditions and system integration costs in certain scenarios. Geothermal energy, utilizing produced water and abandoned wells, significantly reduces carbon emissions through water-source heat pumps for heating and medium-to-low temperature power generation. Waste heat recovery, primarily via heat pump technology, is highly adaptable but limited by a single technical pathway. Wind energy is mainly used for power generation, with experimental studies on wind-driven heating, though applications remain limited. Wave energy shows significant potential in offshore oil and gas fields but is still in early experimental stages. Hydrogen and biomass energy have fewer trials and cases but also hold application potential. Conclusion Overall, photovoltaic power generation, geothermal water-source heat pumps, and waste heat recovery are the most mature technologies and should be prioritized for green energy supply. Green energy solutions should be selected based on regional environmental resources, production capacity, and product characteristics of oil and gas fields. The analysis clarifies the priority of green energy substitution for oil and gas enterprises and highlights key directions for technological breakthroughs. Future research should focus on long-term field studies, establishing full lifecycle databases, and accurately evaluating technical and environmental benefits. Developing multi-energy complementary systems and efficient utilization of abandoned resources will optimize energy matching and achieve cost reduction and efficiency gains.
