As the recovery mechanisms in fractured reservoirs are different fram conventional reservoirs so the EOR is differernt in it. The intention of this study was to analyse improved oil recovery methods- water flooding, immiscible and miscible gas injection in fractured reservoirs as function of fracture intensity, matrix block size, wettability and capillary pressure. It was assumed that the reservoir was a dual porosity system in which a high permeability fracture network is connected to a lower permeability stagnant matrix that contains the majority of the original oil in place.the simulations were conducted using the dual porosity option of the Eclipse 100 simulator and different scenarios were studieh .
