Waterflooding Optimization
Proxy Model Evaluation
AI Algorithms for Optimization
Waterflooding is a critical IOR method for reservoir pressure maintenance and improved sweep efficiency. Optimizing parameters like injection rate, location, and fluid properties significantly enhances oil recovery and reduces costs. However, the computational expense of real reservoir simulations necessitates the use of faster alternatives like AI-based proxy models.
This study systematically evaluates deep learning-based proxy models (ANN, LSTM, GRU, EL) against full-physics reservoir simulations for waterflooding optimization. While proxy models offer computational efficiency and high accuracy metrics (R² up to 0.985), they can struggle with generalization in complex, unseen scenarios, leading to significant deviations in optimal strategies compared to real models.
The study utilized Particle Swarm Optimization (PSO) and Bayesian Optimization (BO) algorithms to find optimal injection and production strategies. These metaheuristic and probabilistic frameworks were applied to both proxy models and the full-physics reservoir simulator, allowing for a direct comparison of optimization outcomes. The results revealed that even highly accurate proxy models could lead to significantly different optimal strategies when compared to full-physics simulations.
