Paper Number: SPE-13514-MS
... Abstract Standard finite difference methods used in reservoir simulation employ large amounts of numerical dispersion. This inherent numerical dispersion causes sharp fronts to be smeared over many grid blocks, and can cause their shapes to be wildly distorted. In this paper we discuss a new...
