Robust Method for Reservoir Simulation History Matching Using Bayesian Inversion and Long-Short-Term Memory Network-Based Proxy

open access: yesSPE Journal, 2022
History matching is a critical process used for calibrating simulation models and assessing subsurface uncertainties. This common technique aims to align the reservoir models with the observed data. However, achieving this goal is often challenging due

gPCE-Based Stochastic Inverse Methods: A Benchmark Study from a Civil Engineer’s Perspective

open access: yesInfrastructures, 2021
In civil and mechanical engineering, Bayesian inverse methods may serve to calibrate the uncertain input parameters of a structural model given the measurements of the outputs.

A Bayesian quantum state tomography along with adaptive frameworks based on linear minimum mean square error criterion

open access: yesNew Journal of Physics, 2023
Quantum state tomography (QST) is essential for characterizing unknown quantum states. Several methods of estimating quantum states already exist and can be classified mainly into three broad classes.

Environmental stress level to model tumor cell growth and survival

open access: yesMathematical Biosciences and Engineering, 2022
Survival of living tumor cells underlies many influences such as nutrient saturation, oxygen level, drug concentrations or mechanical forces. Data-supported mathematical modeling can be a powerful tool to get a better understanding of cell behavior in ...

Bayesian Markov Chain Monte Carlo inversion of surface-based transient electromagnetic data

open access: yesSN Applied Sciences, 2022
Article Highlights 1. We propose a Bayesian MCMC procedure for surface-based TEM data inversion and apply it successfully both in synthetic data and field data. 2.

A practical approach to develop a proper anisotropic rock physics model for media comprising of multiple fracture sets in the absence of sophisticated laboratory/wireline data

open access: yesFrontiers in Earth Science, 2022
For economical production from a fractured reservoir, a characteristic analysis of the fracture parameters like its density and orientation within the reservoir is essential to improve the fluid flow during extraction.

Bayesian inversion and the Tomita–Takesaki modular group [PDF]

open access: yesQuarterly Journal of Mathematics, 2021
We show that conditional expectations, optimal hypotheses, disintegrations and adjoints of unital completely positive maps are all instances of Bayesian inverses. We study the existence of the latter by means of the Tomita–Takesaki modular group and we

Hierarchical Bayesian Inversion of Global Variables and Large‐Scale Spatial Fields

open access: yesWater Resources Research, 2021
Bayesian inversion is commonly applied to quantify uncertainty of hydrological variables. However, Bayesian inversion is usually focused on spatial hydrological properties instead of hyperparameters or non‐gridded physical global variables. In this paper,

Structural Gaussian priors for Bayesian CT reconstruction of subsea pipes

open access: yesApplied Mathematics in Science and Engineering, 2023
A non-destructive testing (NDT) application of X-ray computed tomography (CT) is inspection of subsea pipes in operation via 2D cross-sectional scans. Data acquisition is time-consuming and costly due to the challenging subsea environment. While reducing

A Bayesian approach to the tomographic problem with constraints from geodynamic modeling: Application to a synthetic subduction zone

open access: yesSeismica, 2022
Geodynamic tomography, an imaging technique that incorporates constraints from geodynamics and mineral physics to restrict the potential number of candidate seismic models down to a subset consistent with geodynamic predictions, is applied to a thermal ...
