... the fluid properties of shale oil-water-CO 2 mixtures in nanopores. The findings indicate that the system comprises two phases, namely an oil-rich phase and a water-rich phase, independent of the CO 2 feed. Additionally, a representative pore network of shale is obtained by employing three-dimensional FIB...

... and their continuous change with pressure. Our results indicate that a large amount of intermediate to heavy components are trapped in the nanopores, which causes the condensate yield much lower than expected. Introduction Liquid-rich shale (LRS) reservoirs belong to ultra-tight unconventional formations...

... Abstract With the growing attention on the unconventional energy, the underlying mechanisms of fluid flow in the nanopores is also emphasized. In such nanopores, abnormal phenomena such as velocity slip near the interfaces appears, resulting in the failure of application of the traditional...

... Abstract Gas flow in mudrocks depends on the complex, multiscale connectivity among nanopores, microfractures and macrofractures. Hydraulic fractures stimulate reservoir volume near a horizontal well and create other fractures at all scales. Elsewhere, we have described the Stimulated Reservoir...

... Abstract In this work, we derive an effective mean free path (MFP) model for the confined gases in nanopores of shale gas reservoirs by taking into account the effects of the geometrical termination and the surface-gas interaction of the boundary. Among which, the effect of the surface-gas...

...- and nanopores. On the other hand, the Marls have moderate reservoir-rock quality, and a higher source rock potential. Both the Upper Chalks and the Marls should have major economic potentials. The Lower Chalk has higher porosity and a higher fraction of micro-and nanopores; however, it exhibits poor source rock...

... Abstract Study of gas adsorption in shale nanopores has gained significant attention since it is directly related to reserve estimation and production forecast of shale gas reservoirs. Existing theoretical models generally fail to capture the microscale kinetics which is essential...

... Abstract Current pressure, volume, and temperature (PVT) analysis used in the development of tight oil reservoirs largely omits the impact of nanopores which may drastically alter the phase behavior of confined fluids. Nanopores represent a majority of the total porosity in tight shale...
