The Bayesian framework is the standard approach for data assimilation in reservoir modeling. This framework involves characterizing the posterior distribution of geological parameters in terms of a given prior distribution and data from the reservoir dynamics, together with a forward model connecting the space of geological parameters to the data space. Since the posterior distribution quantifies the uncertainty in the geologic parameters of the reservoir, the characterization of the posterior… 

Data Assimilation in Geomechanics: Characterization of Hydrocarbon Reservoirs

The prediction of the stress field distribution induced by the pore pressure change in deep hydrocarbon reservoirs and the consequent compaction of the porous rock formation is modeled with the aid

Assessment of Sequential and Simultaneous Ensemble-based History Matching Methods for Weakly Non-linear Problems

This thesis investigates the difference between sequential and simultaneous assimilation on toy models and simplified reservoir problems, and assumes that each data depends on the parameters in a specific non-linear fashion.

Accelerated Bayesian inference-based history matching of petroleum reservoirs using polynomial chaos expansions

PCEs are used in simulations based on the black-oil model to estimate model parameters such as porosity, permeability, and exponents of the relative permeability curves to enable accurate estimation of model parameters with two orders of magnitude less number of reservoir simulations compared with MCMC method.

Iterative regularization for ensemble data assimilation in reservoir models

The present work provides a numerical investigation of the performance of the proposed ensemble methods at capturing the posterior and aims at understanding the role of the tunable parameters that arise from the application of iterative regularization techniques.

Parameter sampling capabilities of sequential and simultaneous data assimilation: II. Statistical analysis of numerical results

We assess and compare parameter sampling capabilities of one sequential and one simultaneous Bayesian, ensemble-based, joint state-parameter (JS) estimation method. In the companion paper, part I

Comparison of five different ways to assimilate data for a simplistic weakly nonlinear parameter estimation problem

Four non-iterative parameter estimation methods, applying four different ways to assimilate data, are compared to the (iterative) randomized maximum likelihood (RML) method on problems where the

Parameter estimation by implicit sampling

This work applies implicit sampling to sample the posterior probability density of parameter estimation problems to demonstrate the usefulness of the implicit sampling algorithm with an example from subsurface flow.

Uncertainty Quantification in Bayesian Inversion

Probabilistic thinking is of growing importance in many areas of mathematics. This paper highlights the beautiful mathematical framework, coupled with practical algorithms, which results from



Evaluating Data Assimilation Algorithms

This paper examines the two-dimensional Navier–Stokes equations in a periodic geometry, which has these features and yet is tractable for explicit and accurate computation of the posterior distribution by state-of-the-art statistical sampling techniques.

Investigation of the sampling performance of ensemble-based methods with a simple reservoir model

This paper uses a small but highly nonlinear reservoir model so that it can generate the reference posterior distribution of reservoir properties using a very long chain generated by a Markov chain Monte Carlo sampling algorithm.

An Iterative Ensemble Kalman Filter for Data Assimilation

The ensemble Kalman filter (EnKF) is a subject of intensive investigation for use as a reservoir management tool. For strongly nonlinear problems, however, EnKF can fail to achieve an acceptable data

The ensemble Kalman filter has been successfully applied for data assimilation in very large models, including those in reservoir simulation and weather. Two problems become critical in a standard

This paper compares EnKF with one of the most recently proposed methods, the adaptive Gaussian mixture filter (AGM), on a 2D synthetic reservoir and the Punq-S3 test case and shows that while both methods match the historical data well, AGM is better at preserving the geostatistics of the prior distribution.

Monte Carlo simulation of permeability fields and reservoir performance predictions with SVD parameterization in RML compared with EnKF

Two new algorithms based on truncated singular value decomposition of the dimensionless sensitivity matrix are presented, one which relies only on updating the SVD parameterization at each iteration and one which combines an inner iteration based on an adjoint gradient where during the inner iteration the truncated SVD parameters does not vary.
