“…Finally, the tubing upstream and downstream of the cores and the inhomogeneous velocity profiles at the core entrance and exit contribute additional mixing and erroneously increase the apparent dispersion. The correction for the erroneous contribution of these effects to dispersion associated with our experimental apparatus (as measured previously (Hughes et al (2012) and Honari et al (2013)) was applied to our new results. The concentration profiles were measured at the same conditions of T, p and flow rate for short and long Berea rock cores.…”

“…The core flood apparatus, shown in Figure 2, was designed to allow pulse injection experiments to be conducted through vertically-oriented cores at reservoir conditions as detailed by Hughes et al (2012) and Honari et al (2013). After being placed in the core holder, the core was initially saturated with CH 4 and pressurized to the test pressure using the injection syringe pump.…”

“…To date, it attracts growing attention due to a progressively expanding range of applications of NPMs in catalysis, waste treatment, purification of blood, antibacterial therapy, implant creation, fuel cell technologies, and microelectronics and optics . Another area of high practical interest is natural gas storage in artificial and natural porous reservoirs as well as capture of CO 2 which is used to displace hydrocarbons for enhancing recovery . In most of practical applications, the key factors of NPMs are functional efficiency and physical stability; therefore, significant interest relates to the pores with large surface‐to‐volume ratios, namely, micropores ( r < 2 nm) and mesopores (2 < r < 50 nm).…”

Coherent anti‐Stokes Raman scattering is applied to distinguish dense phases of carbon dioxide adsorbed in mesoporous glass Vycor with pores of 2 nm in radius. Each of the phases is identified by their Raman shifts corresponding to the CO2 band at 1388 cm−1. The results show that the first layer adsorbed on the pore wall and the polymolecular layers adsorbed upon it can be spectroscopically distinguished from each other. Moreover, the spectrum of the polymolecular layers, usually considered as liquid‐like, is found to be noticeably shifted from that of the liquid phase, making these two similar phases also distinguishable. After the onset of condensation, the spectrum of appearing liquid phase is found to be at least threefold broader than that of the bulk liquid. As pressure is increased, it narrows down to the value in the bulk liquid. Observed narrowing reflects size enlargement of liquid clusters, which being initially of nanometer scale in all three dimensions grow up and merge together with pressure increase, finally turning into a single “infinite” cluster, that is, bulk liquid. The results show that Raman‐based methods can help to detect and identify the phases of adsorbate confined in transparent nanoporous hosts. Needing no a priori knowledge about the characteristics of pores and not relying on any modeling or simulation of adsorption, the presented approach is promising to characterize the adsorption mechanisms in mesoporous and microporous materials.

“…For example, Fujii et al (2010) and Zahid et al (2011) argue that saline aquifers are the most viable alternative to store CO 2 because they possess the greatest potential for carbon storage and wide geographical spread. Other studies suggest that CO 2 is a working fluid that can be used to enhance oil recovery (EOR) and natural gas recovery (EGR) (Hughes et al 2012;Liu et al 2015a, b;Middleton et al 2015). Injecting CO 2 into oil or gas reservoirs is promising because it can also offset the costs of CCS (Koide et al 1992;Blunt et al 1993;Gunter et al 1997).…”

This article reports recent developments and advances in the simulation of the CO 2 -formation fluid displacement behaviour at the pore scale of subsurface porous media. Roughly, there are three effective visualization approaches to detect and observe the CO 2 -formation fluid displacement mechanism at the micro-scale, namely, magnetic resonance imaging, X-ray computed tomography and fabricated micromodels, but they are not capable of investigating the displacement process at the nano-scale. Though a lab-on-chip approach for the direct visualization of the fluid flow behaviour in nanoscale channels has been developed using an advanced epi-fluorescence microscopy method combined with a nanofluidic chip, it is still a qualitative analysis method. The lattice Boltzmann method (LBM) can simulate the CO 2 displacement processes in a two-dimensional or three-dimensional (3D) pore structure, but until now, the CO 2 displacement mechanisms had not been thoroughly investigated and the 3D pore structure of real rock had not been directly taken into account in the simulation of the CO 2 displacement process. The status of research on the applications of CO 2 displacement to enhance shale gas recovery is also analyzed in this paper. The coupling of molecular dynamics and LBM in tandem is proposed to simulate the CO 2 -shale gas displacement process based on the 3D digital model of shale obtained from focused ion beams and scanning electron microscopy.
