Streamline Tracing on Curvilinear Structured and Unstructured Grids
https://onepetro.org/SJ/article/7/02/139/109143/Streamline-Tracing-on-Curvilinear-Structured-and
In this paper, a generalization of the Cartesian tracing algorithm is developed for general tensor fields on structured (corner-point) grids and unstructured grids. The extension of the method requires the identification of appropriate volumes and fluxes over which tracing equivalent to the Pollock Cartesian method 2 can be performed. Essential components of the …

[75] It is not trivial to apply the unstructured streamline tracing methods developed in 2-D scenarios to 3-D LGR grids. Here we follow the approach of Jimenez et al. [2010] using a boundary layer approximation, which reduces the 3-D problem to a sequence of 2-D calculations.
Pathline tracing on fully unstructured control-volume grids
https://link.springer.com/article/10.1007/s10596-012-9307-1
The trend toward unstructured grids in subsurface flow modeling has prompted interest in the issue of streamline or pathline tracing on unstructured grids. Streamline tracing on unstructured grids is problematic because a continuous velocity field is required for the calculation, while numerical solutions to the groundwater flow equations provide velocity in …

December 2008 SPE Journal 423. A streamline tracing method is usually based on a fluid particle- tracking concept. First the velocity field is reconstructed from the pressure solution to the flow problem. This velocity field is then integrated by …
Continuous streamline trajectories on complex grids
https://link.springer.com/article/10.1007/s10596-021-10056-z
Abstract. Streamlines have been used for reservoir modeling and flow visualization in the petroleum industry and in computational fluid dynamics. When applied to the calculation of volumetric sweep and the identification of by-passed hydrocarbons for improved oil recovery, it is important that the velocity models that are used to trace trajectories across the cells of a grid …
Streamline simulation - PetroWiki
https://petrowiki.spe.org/Streamline_simulation
Streamline simulation provides an alternative to cell-based grid techniques in reservoir simulation. Streamlines represent a snapshot of the instantaneous flow field and thereby produce data such as drainage/irrigation regions associated with producing/injecting wells and flow rate allocation between injector/producer pairs that are not easily determined by other …
