Nanoscale gas flow in shale gas sediments
Witryna27 maj 2024 · In this study, the gas flow regimes in shale nanopores were classified and analyzed according to Knudsen number. Then the gas flow model considering Darcy flow, slip flow, transition flow, molecular free flow and adsorption effect was proposed to evaluate the gas flow behavior in shale nanopores.

Witryna1 paź 2007 · The process of gas release and production from shale gas sediments is not well understood. Because of adsorptive capacity of certain shale constituents, … WitrynaThe results explain that (1) the production predicted with the numerical method is accurate for the nonlinearity in the model being dealt with properly; (2) the field case shows the veracity of the proposed approach, and gas production and estimated ultimate recovery (EUR) can be evaluated with this model; (3) gas viscosity and Z-factor have …
Witryna4 paź 2024 · In this paper, a new mathematical model of gas flow in shale formations is proposed, which uses gas density instead of pressure as the primary variable. A distinctive feature of the model is to employ chemical potential gradient rather than pressure gradient as the primary driving force. Witryna1 dzień temu · Shale mechanical properties are important for shale gas production, but the magnitudes are difficult to estimate, standard size cores are hard to sample, and secondary interstice generation is ...
