Abstract:

The impact of the hydraulic fracture length, spatial fracture organization and finite conductivity on the effectiveness of oil recovery when a line drive pattern is used is analyzed on the basis of 3D hydrodynamic modeling of two-phase filtration. It is shown that fracture orientation in homogeneous reservoirs has little effect on the final oil recovery factor. Hydraulic treatment in the second row of producers is characterized by more rapid distribution of the high reservoir pressure created by injectors across the area. For this reason, water breakthrough towards the producers of the first row is more rapid. Alongside with that the option of the hydraulic fracturing treatments in the second row of producers is more effective in terms of oil production rate. Hydraulic fracturing performed in the first producing row will result in slower movement of the injected water and more efficient oil recovery. Thus, if hydraulic fracturing treatment is conducted only in the first producing row, the oil recovery factor reaches its maximum value. Hydraulic fracturing treatments in the second producing row are most effective in terms of oil production rate.
