Nanoscale gas flow in shale gas sediments

Witryna12 kwi 2024 · The water-gas flow simulation was performed using PNM developed by Valvatne and Blunt [24]. This method has been further developed and applied in water-oil, and water-gas flow in porous permeable rocks; besides, its accuracy was also verified by comparing the simulated data with the measured data [25], [26].

Witryna1 lis 2024 · An improved approach to study multi-scale real gas transport in fractal shale rocks is proposed to bridge nanoscale PSD and gas filed production. This approach is well validated with field tests. Results indicate the gas production is underestimated without considering a nanoscale PSD. Witryna17 cze 2024 · Abstract The pore size distribution of four shale samples were characterized by and compared between CO2 adsorption, N2 adsorption, MIP and NMR. The results show that CO2 adsorption has an... Witryna22 lis 2024 · In micro- and nanopores may occur various flows including Knudsen, transition, slip and viscous flows (Darcy’s law). As gas flow regime is related to the pore radius, nonuniform pore size distribution causes the coexistence of various flow regimes in tight porous rocks. manitoba hydro thompson mb
