3D induction log modelling with integral equation method and domain decomposition preconditioning
Durra Handri Saputera, Morten Jakobsen, Koen W. A. van Dongen +3
The deployment of electromagnetic (EM) induction tools while drilling is one of the standard routines for assisting the geosteering decision-making process. The conductivity distri…
Randomized maximum likelihood based posterior sampling
Yuming Ba, Jana de Wiljes, Dean S. Oliver +1
Minimization of a stochastic cost function is commonly used for approximate sampling in high-dimensional Bayesian inverse problems with Gaussian prior distributions and multimodal…
An iterative staggered scheme for phase field brittle fracture propagation with stabilizing parameters
Mats Kirkesæther Brun, Thomas Wick, Inga Berre +2
This paper concerns the analysis and implementation of a novel iterative staggered scheme for quasi-static brittle fracture propagation models, where the fracture evolution is trac…
Level Set Methods for Stochastic Discontinuity Detection in Nonlinear Problems
Per Pettersson, Alireza Doostan, Jan Nordström
Stochastic physical problems governed by nonlinear conservation laws are challenging due to solution discontinuities in stochastic and physical space. In this paper, we present a l…
