Optimizing Choke Size to Minimize Sand Production in Oil Wells: A Machine Learning Approach
Abstract
This study investigates the relationship between operational parameters like choke size etc. and sand production in some oilfields, aiming to optimize efficiency while minimizing sand-related challenges. Data visualization revealed trends in sand cut behaviour under varying gross rate, net rate, and BS&W conditions. Three machine learning models artificial neural network (ANN), Random Forest (RF) and extreme gradient boosting (XGBoost) were developed, with XGBoost achieving the highest accuracy. Extreme gradient boosting (XGBoost) outperformed the others by achieving the highest R-squared value of 0.952 and the lowest mean absolute error (MAE) and mean squared error (MSE), demonstrating its superior accuracy in predicting sand cut values. Shapley additive exPlanations (SHAP) analysis highlighted key parameters like manifold pressure, gas rate, and BS&W in predicting sand cut. Optimization using the Mealpy Genetic Algorithm yielded an optimal configuration gross rate of 750blpd, sand cut of 0.25pptb, and BS&W of 5.5%. Sensitivity analysis emphasized monitoring separator pressure and gas rate. The findings demonstrate the potential of integrating machine learning and optimization to enhance decision-making, reduce risks, and improve production efficiency. Recommendations for implementation and future research are provided to ensure sustainable operations.
