Abstract: 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.

Abstract: 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.

Abstract: Asphaltene simulation is performed by modeling asphaltene using physical changes. A pseudo-component framework is used to simulate asphaltene precipitation, asphaltene flocculation, and asphaltene deposition in a subsurface region. The pseudo-component framework for asphaltene simulation treats asphaltene precipitation, asphaltene flocculation, and asphaltene deposition as physical changes of a single component, rather than as chemical changes. Use of the pseudo-component framework for asphaltene simulation reduces complexity of asphaltene simulation. For example, use of the pseudo-component framework for asphaltene simulation enables tracking of asphaltene as it is found in different states (precipitated, flocculated, deposited). Use of the pseudo-component framework for asphaltene simulation enables chemical reactions to be replaced by a flash and adsorption framework. Asphaltene simulation using the pseudo-component framework exhibits stable and fast convergence.
