Zusammenfassung:	The method involves acquiring data characteristic of a fractured reservoir (ACQ), and data obtained from well tests and data relative to development conditions of the reservoir. A pressure gradient related to a flow of a fluid e.g. water, in the fractures is estimated (Gx). A recovery coefficient is calculated (CR) for hydrocarbons i.e. oil. A hydrocarbon recovery time is estimated (T) under an effect of flow of fluid by determining a time required for changing from an initial state to an equilibrium state of matrix blocks by applying two-phase displacement laws from gradient and the data. The reservoir is a weakly water-wet or non-wet fractured reservoir.
