Abstract

Enhanced Oil and Gas Recovery (EOR/EGR) techniques are instrumental in unlocking previously untapped hydrocarbon reserves, crucial in meeting global energy demands. At the heart of these advancements lies chemical thermodynamics, a discipline that provides profound insights into fluid behaviour within reservoirs. This review explores the multifaceted role of chemical thermodynamics in reshaping EOR/EGR strategies, focusing on phase behaviour studies, interfacial phenomena, molecular-level insights, environmental considerations, and future trajectories. Chemical thermodynamics offers a comprehensive understanding of phase equilibria, guiding the design of recovery strategies to optimize hydrocarbon extraction. It elucidates interfacial phenomena, aiding in wettability alterations crucial for enhancing fluid mobility within reservoirs. Furthermore, molecular simulations and computational tools driven by thermodynamic principles offer granular insights, enabling tailored chemical formulations and predictive modeling for efficient recovery techniques. Environmental consciousness, an integral part of chemical thermodynamics in EOR/EGR, fosters the development of eco-friendly formulations. Innovations rooted in this discipline aim to minimize the ecological impact while maximizing recovery rates, aligning with sustainability goals. Looking to the future, chemical thermodynamics heralds a promising era of nanotechnology integration, advanced computational tools, sustainable formulations, and synergy with emerging technologies. These advancements are set to reshape EOR/EGR methodologies, promoting efficiency, sustainability, and environmental stewardship in hydrocarbon extraction. In conclusion, the integration of chemical thermodynamics in EOR/ EGR represents not just a scientific discipline but a transformative force. Its continual evolution is pivotal in shaping a responsible and efficient energy paradigm, meeting global energy needs while preserving environmental integrity
