摘要

Hydrocarbon formation modeling. At least some of the illustrative embodiments are methods including simulating reaction of the formation to hydrocarbon extraction over a plurality of time steps. With each time step, the illustrative method makes a first approximation of migration of saturations for at least one grid block of the plurality of grid blocks (wherein migration of the saturation within at least one time step spans more than one grid block), and then correct the first approximation of migration of saturations for an effect not considered in the first approximation.
