WebOct 6, 2024 · 2.2 Permeability Model of the Micropores Various gas transport mechanisms are coexisted in micropores of the CBM reservoir, including slip flow, Knudsen diffusion and surface diffusion. In this study, a new permeability model for the CBM reservoir was established by coupling three different gas flow regimes. WebPermeability in earth models has three components: natural fracture, distinctive matrix permeability and porosity correlated matrix permeability. While matrix permeability is usually predictable from porosity and diagenesis effects, fracture permeability can be a highly uncertain parameter. The earth model permeability components are calibrated by …
WebBased on measurements of natural sediments as well as resedimented laboratory mixtures of silica, bentonite, and kaolinite powders, we find that our method predicts permeability values that match measured values over four orders of magnitude and among lithologies that vary widely in grain size, mineralogy, and surface area.
