  3. Abstract:
  4. hydraulic fracturing is one of the most prestigious mechanical methods which used as a facile production rate improvement method. Application of this method is in wells with low productivity index. Hydraulic fracturing efficiency depends on various factors, like fracture geometry, fluid composition and stress distribution. But some of them would be ignored. Such as fracture geometry which is neglected due to non-gravity and lack of investigation of DFN statistical population assumption. In this paper we develop a more comprehensive methodology based on fracture geometry, we aim to model one of the gas reservoirs which is naturally fractured, by using well-known commercial software. Based on the methodology, first, we intend to calculate its natural production rate then develop some fractures in diverse directions and calculate the induced production rate. By using a fair comparison, we examine the effect of this method on amount of production rate increment. also extract the optimum fracture geometry (Azimuth and Aperture). As the conclusion we find that with the fracture initiated in a certain degree azimuth and aperture compared to natural fracture, the best amount of production rate increment can be achieved. These results are acceptable based on comparison to field data
