A fully implicit WENO scheme on stratigraphic and unstructured polyhedral grids
(Journal article; Peer reviewed, 2019)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 ... -
Accelerating multiscale simulation of complex geomodels by use of dynamically adapted basis functions
(Journal article; Peer reviewed, 2019)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 ... -
Efficient reordered nonlinear Gauss–Seidel solvers with higher order for black-oil models
(Journal article; Peer reviewed, 2019)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 ...
