Claim:
1. A method for generating an estimation of an incremental recovery for an Enhanced Oil Recovery (EOR) process performed on a naturally-fractured reservoir, the method comprising: using at least one processor, classifying the naturally-fractured reservoir based upon a set of reservoir properties associated with the naturally-fractured reservoir, including determining a classification for each of a plurality of cells in a reservoir model of the naturally-fractured reservoir, each classification assigned from one of a plurality of predetermined fracture types based upon fracture and matrix systems of the reservoir; using the at least one processor, running one or more computer simulations with the reservoir model to simulate for each of the plurality of fracture types and each of a plurality of EOR processes matrix and fracture systems for the reservoir together to account for interaction of the matrix and fracture systems; and generating an estimation of the incremental recovery for at least one EOR process among the plurality of EOR processes based on the classification of the naturally-fractured reservoir and the one or more computer simulations.
