Patent number: 11567058Abstract: A method for simulating a microemulsion system in a chemical enhanced oil recovery process is disclosed. The method includes receiving a geological model of a subsurface reservoir that defines a grid having a plurality of cells, determining a surfactant concentration for each cell based on a volume of surfactant and a volume of water within the cell and independently from a volume of oil in the cell, and simulating fluids flowing in the subsurface reservoir. Results from simulation can be used to optimize a chemical enhanced oil recovery process in a subsurface reservoir.Type: GrantFiled: September 21, 2018Date of Patent: January 31, 2023Assignee: Chevron U.S.A. Inc.Inventors: Xundan Shi, Choongyong Han, Yih-Bor Chang, Christian Wolfsteiner, Baris Guyaguler

Publication number: 20200294413Abstract: Embodiments of methods, systems, and computer-readable media for coupling two or more simulators to simulate a coupled multi-physics model of a subsurface formation are provided. A coupling framework loads one or more simulators as shared libraries into a common process and a common memory space with a first simulator to create the coupled multi-physics model of the subsurface formation. During simulation, the coupling framework controls data exchange between the first simulator and the other simulator(s) through the common memory space and controls execution of the first simulator and the other simulator(s) responsive to the common process. In the event of two-way coupling, the coupling framework can receive feedback from the other simulator(s) and alter execution of the first simulator. In the event of grid misalignment, the coupling framework can map data between the first simulator and the other simulator(s) such as in a globally conservative (e.g., mass, energy, etc.) manner.Type: ApplicationFiled: March 12, 2020Publication date: September 17, 2020Applicant: CHEVRON U.S.A.

Patent number: 8805660Abstract: A method, system and apparatus are disclosed for coupling independent reservoir and surface facility network simulators. A reservoir simulator is configured to simulate fluid flow in subterranean reservoirs and a surface facility network simulator is configured to simulate fluid flow in production equipment. Simulation of fluid flow in a subterranean reservoir is initiated using the reservoir simulator. Simulation of fluid flow in production equipment is initiated using the surface facility network simulator. The simulated fluid flow in the production equipment includes fluids produced from the subterranean reservoir. The simulation of fluid flow in the subterranean reservoir is coupled with the simulation of fluid flow in the production equipment using a sub-domain inflow performance relationship.Type: GrantFiled: November 10, 2011Date of Patent: August 12, 2014Assignees: Chevron U.S.A.

Patent number: 7627461Abstract: A method for enhancing the allocation of fluid flow rates among a plurality of well bores in fluid communication with at least one subterranean reservoir is disclosed. An objective function and system equations are generated which utilize constraint violation penalties associated with soft constraints. The soft constraints are constraints which may be violated if necessary to arrive at a feasible solution to optimizing the objective function and the system equations. The fluid flow rates are then allocated among the well bores as determined by the optimizing of the objective function and system equations. Fluid flow rates among well bores, particularly those exhibiting similar fluid characteristics, may be related to one another. Initial flow rates of components (oil, gas, and water) and pressures in the well bores may be determined by an initial simulation run.Type: GrantFiled: May 25, 2004Date of Patent: December 1, 2009Assignee: Chevron U.S.A.
