Hydraulic fracture is known as one of the effective methods for producing or being caused a change in the physical structure of a reservoir rock. In oil and gas reservoirs which have been fractured by a hydraulic approach, this method causes that a production well and the time of reservoir production increase. In this research, fracture analysis have been comprised with the outputs produced by previous models. Its results show that the opening intersection produced by hydraulic fracture has been being changed in various time during pumpage, therefore, the fracture should be kept open by propanent substances. In the next stage, the amount of porosity pressure in the trend of the fracture is considered. In this survey, two parameters, i.e. the fracture measure and the change of pore pressure have been obtained using the hydraulic fracture modeled process under the actual condition of pay zone and its confining layers, and by the finite element approach. In this method, pumping processing has been assigned for fluid and propanent. At the end, by making a comparison between these result and the results obtained from previous studies, it can be found out that this approach is applicable and efficient.
