Higher-order spatial discretization has been used by many authors to reduce numerical diffusion and mitigate grid-orientation effects. EOR processes are particularly susceptible to numerical diffusion, since the active chemical substances are often transported by linear or weakly nonlinear waves. Mo...

Two decades ago, Helge Holden proposed seven guidelines to improve the way new achievements and results in scientific computing were presented, evaluated, and compared in contemporary scientific literature. In this essay, written as a tribute to Helge on his 60th birthday, I revisit the guidelines a...

Equations modelling multiphase/multicomponent flow in porous media are widely studied by the hyperbolic community, e.g., as examples of problems with nonconvex and spatially-dependent flux. Various types of high-resolution methods have been developed to solve these equations, but few have managed to...

Large-scale storage of CO2 in saline aquifers is considered an essential technology to mitigate carbon emissions. The injected CO2 will form a buoyant plume that can migrate long distances as a thin sheet under a sloping impermeable caprock. The plume migration can be described by mass conservation ...
