Abstract
A method and system are described for creating subsurface models that involve the use of different grain sizes for simulating fluid flow in reservoir simulators. The method includes constructing a subsurface model for a subsurface region and using the subsurface model in simulations and in hydrocarbon operations, such as hydrocarbon exploration, hydrocarbon development, and/or hydrocarbon production.
