An Improved Parameter Dimensionality Reduction Approach Based on a Fast Marching Method for Automatic History Matching
2022
Fluid Dynamics & Materials Processing
History matching is a critical step in reservoir numerical simulation algorithms. It is typically hindered by difficulties associated with the high-dimensionality of the problem and the gradient calculation approach. Here, a multi-step solving method is proposed by which, first, a Fast marching method (FMM) is used to calculate the pressure propagation time and determine the single-well sensitive area. Second, a mathematical model for history matching is implemented using a Bayesian framework.
