Optimizing Reservoir Performance through Advanced Water Flooding and Thermal Recovery Methods

Abstract

Enhanced Oil Recovery (EOR) techniques, particularly water flooding and thermal recovery, play a crucial role in maximizing hydrocarbon recovery from mature and complex reservoirs. These methods have evolved significantly due to advancements in reservoir characterization, numerical modeling, and operational optimization, leading to improved efficiency, reduced operational costs, and minimized environmental impact.

This review provides a comprehensive analysis of water flooding strategies, including secondary and tertiary water injection, optimized injection patterns, and sweep efficiency enhancement. Thermal recovery methods, such as steam injection, cyclic steam stimulation, and in-situ combustion, are examined with emphasis on their mechanisms, operational challenges, and performance optimization. The integration of modern simulation tools, real-time monitoring systems, and digital twin technologies enables operators to model reservoir behavior accurately, optimize injection strategies, and predict production outcomes under varying operational scenarios.

Key challenges, such as reservoir heterogeneity, scaling and corrosion, and energy requirements, are addressed along with optimization strategies for overcoming these limitations. The review also highlights future directions, including the application of artificial intelligence, hybrid EOR approaches, and environmentally sustainable technologies, which are expected to further enhance reservoir performance and operational efficiency.
