Patent number: 11840927Abstract: A method may include determining, during a first time step within an iterative simulation process, various pseudo-pressure values based on model data. The method may include determining, during the first time step, a first set of skin factor values for the wellbore radial grid portions using the pseudo-pressure values. The method may include simulating, during the first time step, a first well production rate for a well within a reservoir region of interest using the first set of skin factor values and a first pressure distribution for the reservoir region of interest. The method may include simulating, during a second time step within the iterative simulation process, a second well production rate for the well using a second set of skin factor values and a second pressure distribution for the reservoir region of interest.Type: GrantFiled: September 18, 2020Date of Patent: December 12, 2023Assignee: SAUDI ARABIAN OIL COMPANYInventors: Ali Haydar Dogru, Xiang Yang Ding

Patent number: 11454105Abstract: An unstructured grid model with actual well trajectory of individual multilateral wells of a subsurface reservoir is formed. Well trajectory data obtained during drilling of the wells and corresponding to well trajectory data stored as a structured grid model is provided as an input data set for unstructured grid simulation. The unstructured grid model may be formed in a computerized mainframe processor system, or by parallel reservoir simulation by processor nodes of a multicore processor of parallel processor nodes synchronized and under control of a master node.Type: GrantFiled: April 25, 2019Date of Patent: September 27, 2022Assignee: Saudi Arabian Oil CompanyInventors: Xiang Yang Ding, Larry Siu-Kuen Fung

Patent number: 11379640Abstract: Reservoir management based on unstructured grid reservoir simulation is improved with machine learning based intelligent automation. Reservoir heterogeneity, geological internal boundary features and well geometry complexity are taken into account to automatically detect well zone and focusing reservoir area by calculating the region-of-interests in the model and defining cell spacing for grid coarsening and refinement in the reservoir. Data points for wells in the reservoir are grouped into reservoir regions according to datasets organized as a convex hull, which is a minimum convex set in spatial geometry which encloses the totality of such data points. The reservoir regions form a basis for grid spacing utilized in the reservoir model.Type: GrantFiled: January 8, 2020Date of Patent: July 5, 2022Assignee: Saudi Arabian Oil CompanyInventor: Xiang Yang Ding

Patent number: 11352855Abstract: Orthogonal unstructured grids are automatically constructed for a field or reservoir model with two types of internal boundaries: complex wells and faults, or other discontinuities. The methodology is used to constructed simulation grids for reservoirs or fields which contains both complex fault planes and multi-lateral wells. A hierarchical grid point generation, prioritization, conflict point removal system is provided enabling the use of unconstrained Delaunay triangulation. High-quality orthogonal unstructured grids are produced with good convergence properties for reservoir simulation.Type: GrantFiled: March 20, 2020Date of Patent: June 7, 2022Assignee: Saudi Arabian Oil CompanyInventors: Larry Siu-Kuen Fung, Xiang Yang Ding, Ali H.
