Continuous Hyper-parameter OPtimization (CHOP) in an ensemble Kalman filter
Xiaodong Luo, Chuan-An Xia
Practical data assimilation algorithms often contain hyper-parameters, which may arise due to, for instance, the use of certain auxiliary techniques like covariance inflation and l…
A Decision Support System for Multi-target Geosteering
Sergey Alyaev, Erich Suter, Reidar Bratvold +2
Geosteering is a sequential decision process under uncertainty. The goal of geosteering is to maximize the expected value of the well, which should be defined by an objective value…
Ensemble-based kernel learning for a class of data assimilation problems with imperfect forward simulators
Xiaodong Luo
Simulator imperfection, often known as model error, is ubiquitous in practical data assimilation problems. Despite the enormous efforts dedicated to addressing this problem, proper…
Efficient big data assimilation through sparse representation: A 3D benchmark case study in seismic history matching
Xiaodong Luo, Tuhin Bhakta, Morten Jakobsen +1
In a previous work \citep{luo2016sparse2d_spej}, the authors proposed an ensemble-based 4D seismic history matching (SHM) framework, which has some relatively new ingredients, in t…
An Ensemble 4D Seismic History Matching Framework with Sparse Representation Based on Wavelet Multiresolution Analysis
Xiaodong Luo, Tuhin Bhakta, Morten Jakobsen +1
In this work we propose an ensemble 4D seismic history matching framework for reservoir characterization. Compared to similar existing frameworks in reservoir engineering community…
Iterative ensemble smoother as an approximate solution to a regularized minimum-average-cost problem: theory and applications
Xiaodong Luo, Andreas S. Stordal, Rolf J. Lorentzen +1
The focus of this work is on an alternative implementation of the iterative ensemble smoother (iES). We show that iteration formulae similar to those used in \cite{chen2013-levenbe…
