Review of the Hydraulic Fracturing Process based on Preceding Studies Conducted in Iran and the United States

Less than two centuries have passed since the discovery of the first oil well in the world. Black gold has created a huge transformation in the daily lives of human societie; As life without oil and oil products is unthinkable for today s human being. Nevertheless, cheap oil reserves have been completed and in most parts of the world production has declined. Due to the limited fossil resources and their non-renewal, measures are being taken to recycle more oil from reservoirs. Increasing the recovery and improving the coefficient of recycling of reservoirs by inducing wells using hydraulic fracture operations is one of the most effective methods for optimal production. In this study, the process of hydraulic fracturing and preceding studies conducted in Iran and foreign countries will be discussed. Investigating this process, according to the studies, showed that the hydraulic fracturing is an effective way to increase the economic efficiency and utilization of oil wells, and considering that the studies carried out in Iran are more in the form of numerical analysis and modeling and simulation in this field and field studies have been neglected in this regard. And due to the advantages of this method in economic fields, more attention is paid to oil researchers in this area
