Paper Number: SPE-203949-MS
... been developed for structured grids and needs to be adapted to the unstructured case. Second, the use of unstructured grids that do not satisfy the K-orthogonality property may require advanced numerical schemes that preserve the accuracy of the results and reduce potential grid orientation effects...

... compressibility and needs to be incorporated in realistic reservoir simulations ( Aziz and Settari, 1979 ). However or main goal here is to analyze the performance of our numerical schemes under the effects of the compressibility parameter that incorporates rock heterogeneity and exhibiting spatial variability...

Paper presented at the SPE Reservoir Simulation Symposium, February 11–14, 2001
Paper Number: SPE-66344-MS
... Abstract Higher order numerical schemes are necessary to get good front resolution when modelling reservoirs using practical block sizes. Methods for such schemes presented to date have focussed on situations where the grids are somewhat regular. To be useful, implementations are required...

... of grid makes the standard linear approach inefficient for the near-well flow modelling. In this paper, new numerical schemes, which are based on logarithmic approach, are proposed to improve the standard linear approach for the near-well modelling. In particular, a multi-point and a two-point flux...

... precision at the local level. For such a method to be successful, a dynamic data structure is needed as well as a higher order numerical scheme for pressure and saturation. The main difficulties are to approximate the fluid fluxes at the interface of two blocks belonging to two regions having been refined...
