When the shale gas is extracted from the reservoir, the exchange of gas between hydraulic fractures, matrix, and nanopores occurs and it triggers complicated interactions in shale plays. This thesis focuses on the interactions and theoretical models are obtained. Firstly, an apparent permeability model for shale matrix is developed. Secondly, a fully coupled reservoir simulation model is proposed to evaluate shale gas performance. Thirdly, a simulation model coupling the impact of water flow back, gas flow and shale deformation is developed to investigate two phase flow performances. These models are implemented to evaluate field gas production.
