Predicting Calcium Barriers in the Xihu Depression from Sparse Well Logs

In the sand-rich Xihu Depression, identifying potential sealing beds is a challenge when continuous mudstone barriers are scarce. This study tackles that problem directly, predicting calcium content from conventional well logs with impressive accuracy, an R² of 0.89 and RMSE of 0.52 percentage points. By then classifying six target lithologies, AdaBoost emerged as the strongest model, achieving 0.88 accuracy on internal tests and 0.82 on an independent well.
