Abstract

When natural gas is extracted from coal-seam/shale gas reservoirs, the exchange of gas mass between matrix blocks and fractures occurs and this change triggers complex matrix-fracture interactions The primary goal of this thesis is to investigate the impact of matrix-fracture interactions on the evolution of permeability for the rigorous evaluation of unconventional gas production. This goal was achieved through the development of a series of permeability models under the influence of the matrix-fracture interactions. These models were implemented into a multi-scale numerical simulation model for the forecast of shale gas production .
