..., with a short elastic energy development cycle and low crude oil recovery. Consequently, the concept of enhanced oil recovery is continuously emphasized throughout the extraction process. Imbibition has been extensively utilized in the development of various reservoirs to enhance oil recovery. Spontaneous...

..., the porous media was saturated with the wetting fluid and the non-wetting fluid was allowed to displace the wetting fluid (drainage) from the porous media. Later, imbibition simulations were performed as the wetting fluid was injected and the non-wetting fluid was recovered. In the second aspect, we...

... ). The fracturing water leak-off forms a high water-saturation zone near fracture-matrix interface, decreasing kro during flowback and post-flowback processes ( Bennion et al. 1996 ). On the other hand, imbibition of fracturing water into the rock matrix has been considered as a driving force for oil production...

In each simulation run, stress-dependent permeability phenomena during fracturing and flowback are modeled to more closely simulate proppant crushing and embedment. Our model carefully simulates the matrix, natural, and hydraulic fractures separately, because each...
