An implicit local time-stepping method based on cell reordering for multiphase flow in porous media
Multiscale Simulation of Flow and Transport in Porous Media
Nonlinear domain decomposition scheme for sequential fully implicit formulation of compositional multiphase flow
Robust Nonlinear Newton Solver With Adaptive Interface-Localized Trust Regions
The interplay of multiphase-flow effects and pressure/volume/temperature behavior encountered in reservoir simulations often provides strongly coupled nonlinear systems that are challenging to solve numerically. In a sequentially implicit method, many of the essential nonlinearities are associated w...
Optimized CO2 storage in sloping aquifers: Estimation of physical and chemical immobilization potential and retardation along migration path in open storage solutions
Efficient reordered nonlinear Gauss–Seidel solvers with higher order for black-oil models
The fully implicit method is the most commonly used approach to solve black-oil problems in reservoir simulation. The method requires repeated linearization of large nonlinear systems and produces ill-conditioned linear systems. We present a strategy to reduce computational time that relies on two k...
Implicit high-resolution compositional simulation with optimal ordering of unknowns and adaptive spatial refinement
Accelerating multiscale simulation of complex geomodels by use of dynamically adapted basis functions
A number of different multiscale methods have been developed as a robust alternative to upscaling and as a means for accelerated reservoir simulation of high-resolution geomodels. In their basic setup, multiscale methods use a restriction operator to construct a reduced system of flow equations on a...
A fully implicit WENO scheme on stratigraphic and unstructured polyhedral grids
Many authors have used higher-order spatial discretizations to reduce numerical diffusion, which can be particularly pronounced when simulating EOR processes involving active chemical substances that are transported by linear or weakly nonlinear waves. Most high-resolution methods reported in the li...
