Abstract
Summary
In this paper we propose Bayesian history matching workflow with the application of machine learning algorithms and discuss its implementation to synthetic and real hydrodynamic models. Since the traditional Bayesian approach is computationally intensive we suggest substituting simulator runs with a machine-learning algorithm to estimate the objective function value for generated models. For this purpose, we consider Kernel Ridge Regression trained on prior models obtained from the Latin Hypercube Sampling procedure. The workflow allows to reduce the uncertainty of model parameters and to indicate objective function sensitivity to model parameters.
