The importance of shale gas production in altering the global energy system is growing. There is consensus that hydraulic fracturing in horizontal wells is the most cost-effective and efficient method for accessing shale gas resources. For hydraulic fracturing to be successful in the long run as shale gas production expands, a number of key characteristics must be optimized. The research focuses on the development of reservoir simulators (Companion of St. Michael and St. George-International Monetary Exchange (CMG-IMEX)) and analyzing the parameters, which have a major impact on gas flow in the shale gas reservoir. In the process of gas flow characterization, the approach is to consider a dual porosity model for analyzing the reservoir simulation model of a shale gas reservoir. With the use of a model, we are able to analyze the flow of shale gas from tight reservoirs through the conductive fractures to the wellbore. The development of this research could lead to enhanced production from the shale gas wells.
