Consistent upwinding for sequential fully implicit multiscale compositional simulation
Efficient Solvers for Field-Scale Simulation of Flow and Transport in Porous Media
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...
