Adaptive streamline tracing for streamline simulation on irregular grids

Håkon Hægland, Helge Dahle, Geir Terje Eigestad, Knut-Andreas Lie, Ivar Aavatsmark & Håkon Hægland
Streamline methods have shown to be effective for reservoir simulation. Streamline simulation relies on an efficient an accurate calculation of streamlines and time-of-flight coordinates (TOF). Streamlines are commonly computed on a cell-by-cell basis using a flux interpolation in the semi-analytical Pollock's method. An alternative method is a grid-cell corner-point velocity interpolation, which is able to reproduce uniform flow in three spatial dimensions. For this method numerical integration of streamlines is required. The shape of streamlines...
