Adaptive and accuracy-aware multiple data assimilation in a three step framework
Kyle Ivey, Matthias Morzfeld, Chaoyi Wang +4
The ensemble smoother with multiple data assimilation (ES-MDA) is an algorithmic framework for the ensemble-based solution of inverse problems in reservoir engineering (and beyond)…
Multilevel well modeling in aggregation-based nonlinear multigrid for multiphase flow in porous media
Chak Shing Lee, François P. Hamon, Nicola Castelletto +2
A full approximation scheme (FAS) nonlinear multigrid solver for two-phase flow and transport problems driven by wells with multiple perforations is developed. It is an extension t…
An Aggregation-based Nonlinear Multigrid Solver for Two-phase Flow and Transport in Porous Media
Chak Shing Lee, François P. Hamon, Nicola Castelletto +2
A nonlinear multigrid solver for two-phase flow and transport in a mixed fractional-flow velocity-pressure-saturation formulation is proposed. The solver, which is under the framew…
Phase-field modeling of rock fractures with roughness
Fan Fei, Jinhyun Choo, Chong Liu +1
Phase-field modeling -- a continuous approach to discontinuities -- is gaining popularity for simulating rock fractures due to its ability to handle complex, discontinuous geometry…
Multigrid reduction preconditioning framework for coupled processes in porous and fractured media
Quan M. Bui, Francois P. Hamon, Nicola Castelletto +3
Many subsurface engineering applications involve tight-coupling between fluid flow, solid deformation, fracturing, and similar processes. To better understand the complex interplay…
Hybrid mimetic finite-difference and virtual element formulation for coupled poromechanics
Andrea Borio, François Hamon, Nicola Castelletto +2
We present a hybrid mimetic finite-difference and virtual element formulation for coupled single-phase poromechanics on unstructured meshes. The key advantage of the scheme is that…
