Abstract

According to increasing demand of the country for more production rates and output from oil reservoirs, it's necessary to re-activate the oil wells in Iran. Oil production in overtime Reduces, The reason of this event is decreased reservoir's Pressure and Closure the cracks and microscopic holes. Hydraulic fracture as a method for stimulating oil reservoirs related to various factors including the characteristics of the environment which the fracture grows. Mechanical properties of the layers recognized as the one of the most effective parameters on the progress of hydraulic fracture and its geometry. In this study, we try to indagate the various factors involved in hydraulic fracture and the effect of each of them on hydraulic fracture until reduce both operation costs and better and more efficient failure. In this research, Numerical modeling was done by ABAQUS software in 10 different cases and then, the effect of the each input parameters on the hydraulic fracture pressure was investigated by performing Sensitivity analysis. Actually these input parameters are well's data and including Young's modulus, minimum and maximum horizontal stress, vertical stress, tensile strength, poison’ s ratio and pore pressure. Required information is obtained from excavated wells in carbonate rocks in Iran. The results show's minimum horizontal stress has the most effect on the hydraulic fracture pressure and parameters such as vertical stress and Young's modulus are not effective in determination of hydraulic fracture pressure.
