At present, hydraulic fracturing of horizontal wells has become a widely used technology in stimulating tight oil reservoirs. However, the treatment of hydraulic fractures in numerical simulation of multi-fractured horizontal wells in tight oil is excessively ideal. Effects of some fracture properties on numerical simulation of tight oil are usually not taken into consideration. Actually, fracture geometry in the reservoir is complex and fracture permeability is not a constant value. Numerical model without these factors may lead to a significant error in forecasting the reservoir response. Hydraulic fracturing and horizontal wells are not new tools for the oil and gas industry. The first fracturing experiment was in 1947 and the process was accepted as commercial by 1950. The first horizontal well was in the 1930’s and horizontal wells were common by the late 1970’s. Even shale gas, especially from the Devonian shales, is not new producing intervals.
