Abstract Scope Accurate numerical modeling of fluid transport is essential in reservoir management. Higher-order methods help to improve accuracy by reducing the diffusion, which common for all first order methods. In this paper, we present an implementation a MUSCL-type second-order finite volume method and demonstrate its capabilities on 2D 3D unstructured grids. This includes corner point grids that are typically used modeling. Methods, Procedures, Process A second compared standard terms...
Abstract Subsurface reservoirs are large complex systems. Reservoir flow models defined on grids that follow geology with relatively block sizes to make consistent simulations feasible. engineers rely established reservoir simulation software model fluid flow. Nevertheless, front position inaccuracies and smearing may cause significant errors it hard predict hydrocarbon production efficiency. We investigate higher-order methods reduce these undesired effects without refining the grid, thus...
Improved and enhanced oil recovery methods require sophisticated simulation tools to predict the injected flow pass together with chemical reactions inside it. One approach is application of higher order numerical schemes avoid excessive diffusion that very typical for transport processes. In this work we provide a first step towards applicable on general polyhedral corner-point grids typically used in reservoir simulation. We compare two possible approaches linear reconstruction slope...
