Patent number: 9626466Abstract: A variable discretization method for general multiphase flow simulation in a producing hydrocarbon reservoir. For subsurface regions for which a regular or Voronoi computational mesh is suitable, a finite difference/finite volume method (“FDM”) is used to discretize numerical solution of the differential equations governing fluid flow (101). For subsurface regions with more complex geometries, a finite element method (“FEM”) is used. The invention combines FDM and FEM in a single computational framework (102). Mathematical coupling at interfaces between different discretization regions is accomplished by decomposing individual phase velocity into an averaged component and a correction term.Type: GrantFiled: August 12, 2011Date of Patent: April 18, 2017Assignee: ExxonMobil Upstream Research CompanyInventors: Yahan Yang, Linfeng Bi, Weidong Guo, Rossen Parashkevov, Xiaohui Wu
