Summary

A proposed project aims to replace traditional numerical simulations with a machine learning pipeline for optimizing geothermal injection well placement and predicting thermal breakthrough probability. Geothermal reservoir management currently faces challenges with computationally intensive simulations and the risk of premature production well cooling due to imprecise injection. This initiative will train XGBoost and Artificial Neural Network (ANN) models on historical sensor data, including flow rates, temperature gradients, and spatial distances. The goal is to instantly identify high-probability zones for thermal breakthroughs and provide recommendations for optimal new injection well locations, thereby extending power plant operational life. The project plans to utilize Python with libraries like pandas, numpy, scikit-learn, xgboost, matplotlib, and seaborn, targeting a two-week completion with a two-person team.

Key takeaway

For geothermal reservoir engineers tasked with optimizing injection well placement, this project highlights a shift from costly simulations to predictive machine learning. You can utilize historical sensor data to train XGBoost and ANN models, enabling instant identification of thermal breakthrough risks. This approach offers a faster, data-driven method to recommend optimal well locations, directly extending power plant operational life and improving resource management. Consider integrating similar ML pipelines into your reservoir management strategies.
