WELL PLUG INTEGRITY

Claims

Some implementations include a method for predicting a plug leak in a well during hydraulic fracturing operations. The method may include: generating a training dataset that includes feature samples and prediction samples, where the feature samples include values ​​derived from past pressure pulses in the well with or without other fracturing treatment data, and the prediction samples include values ​​derived from digital acoustic detection (DAS) sensors located in the well; and training, with the training dataset, a machine learning system to predict plug leaks during hydraulic fracturing operations based on pressure with or without other treatment data indicating one or more current pressure pulses.
