Hydraulic fracturing operation is one of the key technologies in order to stimulate oil and gas wells in sand stone reservoirs. Field data relating to the hydraulic fracturing operation are mostly available as pressure-time curves. The optimization of the hydraulic fracturing parameters is not possible with only this information. So the designing and controlling the development process of hydraulic fracturing are possible only with rely on complex mathematical and numerical models. The aim of this study is to optimize the effective parameters on designing of the hydraulic fracturing process in an Iranian oil reservoir with sandstone reservoir rocks. For this purpose the parameters of pump flow rate and hydraulic fracture half length have been optimized. In this study first variable pump flow rates scenarios have been investigated. The scenarios to determine the optimum value for hydraulic fracturing half length have been designed after determining of the optimal pump flow rate. In this study the calculation results in addition to the pseudo three-dimensional hydraulic fracturing model (P3D) have also provided with the hydraulic fracturing two-dimensional modeling including PKN, KGD and Radial models.
