Robust machine-learning workflow for subsurface geomechanical characterization and comparison against popular empirical correlations

作者:

Highlights:

• Recovery of fossil/ geothermal energy requires subsurface mechanical characterization.

• Robust machine learning workflow is proposed for synthesizing sonic travel time logs.

• New data preprocessing and model stability assessment ensures the robustness.

• Multivariate adaptive regression spline performs better than neural network.

• Multivariate adaptive regression spline performs better than empirical models.
