    • Robust nonlinear Newton solver with adaptive interface-localized trust regions 

      Klemetsdal, Øystein; Møyner, Olav; Lie, Knut-Andreas (Peer reviewed; Journal article, 2019)
      The interplay of multiphase flow effects and PVT behavior encountered in reservoir simulations often gives strongly coupled nonlinear systems that are challenging to solve numerically. In a sequentially implicit method, ...

    • The application of flow diagnostics for reservoir management 

      Møyner, Olav; Krogstad, Stein; Lie, Knut-Andreas (Journal article; Peer reviewed, 2014)
      Flow diagnostics, as referred to herein, are computational tools derived from controlled numerical flow experiments that yield quantitative information regarding the flow behavior of a reservoir model in settings much ...
