Data Leakage: When a Geological Model Knows Too Much

A machine-learning model can achieve excellent test results for the wrong reason. Data leakage occurs when information unavailable in a real prediction accidentally enters training or evaluation. In geoscience, leakage can be subtle because observations are linked by wells, locations, time, and geological units. The Same Well in Two Sets Imagine dividing individual depth measurements randomly between training and test data. Samples from the same well may appear in both sets.
