Abstract

Hydraulic fission has been successfully performed in the world for more than several decades and its application is increasing. However, in our country, due to the high pressure of reservoirs, there is not much interest in this work and few cases that have been performed, have not been successful due to inadequate geomechanical studies. The aim of this study is to investigate the effect of well characteristics and well inclination on fracture pressure. One of the most important issues in hydraulic fission is the right location for hydraulic fission. In other words, in which layer or depth, this operation should be performed. The effective parameters in selecting the appropriate depth for hydraulic fission include the degree of water saturation, that porosity, and geomechanical properties of the reservoir in order of their priority. Porosity affects on well yield and geomechanical properties affect on fracture pressure. There are two views to study and analyze the hydraulic fracture process. One is the mechanical fracture method and the other is the classical method, based on the theory of elasticity. The geomechanical parameters affecting the fracture pressure include Young's modulus, Poisson's coefficient and Biot coefficient. Poisson's coefficient was determined to be the most effective parameter on hydraulic fracture pressure and fission. In this study, the parameters affecting the fracture pressure were investigated.
