A method of modeling hydrocarbon flow from a fractured unconventional reservoir, where the formation has variability in stimulated reservoir properties caused by multi-stage fracturing treatment. A map is created which divides the formation into a plurality of closed production regions, each of which in turn is divided into a plurality of flow sub-systems extending between fractures in the formation. Production behavior is then calculated for each flow sub-system based on the geography and characteristics of the individual flow sub-system. Region hydrocarbon flow for each closed production region is determined by coupling the calculated production behavior of the flow sub-systems and the reservoir hydrocarbon flow can be modeled by aggregating the region hydrocarbon flows. Type curves showing the modeled hydrocarbon flow at selected points in time can then be plotted.

A method for the estimation of oil recovery factor in a foam flooded hydrocarbon reservoir. The hydrocarbon reservoir is divided into three sweep sub-zones, with sweep efficiency and displacement efficiency for each zone being estimated. The oil recovery factor is determined as a function of porous volume injected, based on the sweep efficiency and displacement efficiency.
