The adsorption of hydrocarbon (pure CH4 and C2H6) on illitic clay was investigated at temperatures 333, 363, 393 K (60, 90, 120 °C) over a range pressures up to 30 MPa using grand canonical Monte Carlo (GCMC) simulations. We first discussed the comparability molecular simulation results with experimental measurements. Our indicate that excess are comparable measurements if they both expressed per unit surface area available for instead mass. gas density profiles C2H6 is mainly affected by...
CO2 injection into oil reservoirs is expected to achieve enhanced recovery along with the benefit of carbon storage, while application potential this strategy for shale unclear. In work, a numerical model multiphase flow in developed investigate impacts nano-confinement and composition on storage efficiency. Two oils different maturity levels are selected, higher-maturity containing lighter components. The results indicate that saturation pressure lower-maturity continues increase increasing...
Abstract Pore structure characterization and its effect on methane adsorption shale kerogen are crucial to understanding the fundamental mechanisms of gas storage, transport, reserves evaluation. In this study, we use 3D scanning confocal microscopy, electron microscopy (SEM), X-ray nano-computed tomography (nano-CT), low-pressure N 2 analysis analyze pore structures shale. Additionally, behavior shales with different is investigated by molecular simulations. The results show that SEM image...
An analytical model for gas transport in shale media is proposed on the basis of linear superposition convective flow and Knudsen diffusion, which free tangential momentum accommodation coefficient. The present takes into effect pore shape real gas, successfully validated against experimental data Lattice–Boltzmann simulation results. Gas noncircular nanopores can be accounted by a dimensionless geometry correction factor. In continuum‐flow regime, has relatively minor impact capacity;...
Nanopore structure and its multiscale feature significantly affect the shale-gas permeability. This paper employs fractal theory to build a permeability model, particularly considering effects of flow within pore space. Contrary previous studies which assume bundle capillary tubes with equal size, in this research, model reflects various regimes that occur pores takes measured pore-size distribution into account. The regime different scales is individually determined by Knudsen number. gas...
A model for real gas flow in shale matrices is proposed and consists of two main steps: (a) developing a microscopic (single pore) by generalizing our previously reported Extended Navier‐Stokes Equations (ENSE) method (b) using fractal theory concepts, up‐scaling the single pore to macroscopic scale. prominent feature up‐scaled predictor apparent permeability (AP). Both models are successfully validated with experimental data. The impact deviation behavior from ideality (real effect) on...
Accurate rate of penetration (ROP) prediction is important for optimizing drilling parameters, selecting tools, improving efficiency, and reducing operation cost. The study area deep lacustrine shale oil in Mahu, with alkaline sediment strong non-homogeneity, the spatial variation ROP fast cannot be accurately predicted. selection parameters tools are not targeted, especially there a good correspondence between formation resistivity by statistics. In paper, new method well-seismic joint...
Summary Abrasive water jet (AWJ) rock slotting has great potential in hydraulic fracturing. The perforation efficiency of AWJ is higher than that conventional perforation. There an insufficient comprehension slotting, including slot evolution, mechanism, and parameter influence. For this study, we conducted experiments by reciprocating nozzle to investigate the effects type, time, rate, abrasive volume concentration, distance, moving rate on parameters specific energy breaking. exhibits...
Apparent permeability is an important input parameter in the simulation of shale gas production. Most apparent models assume a single pore size. In this study, we develop theoretical model for quantifying effect size distribution on permeability. The accounts nonuniform sizes, rarefaction effect, and characteristics. validated against available experimental data. Theoretical calculations show that larger radius, Moreover, increases with increase width distribution, being much more pronounced...
