“…Numerical simulation is another useful and high-efficiency method to evaluate the CO 2 injection process and investigate the effect of geological heterogeneity and CO 2 flow behavior in CS-EGR projects. − Iddphonce et al reviewed the performance of the continuous CO 2 injection technique and CO 2 huff-n-puff technique based on simulations. The CO 2 injection can be used in hydraulically fractured shale, and the CO 2 injection techniques can lead up to 26% more CH 4 production and store more than 60% of the injected CO 2 for continuous CO 2 injection, while more CO 2 is reproduced for the CO 2 huff-n-puff scenario.…”

The mechanisms of adsorption of methane (CH 4 ) and carbon dioxide (CO 2 ) are still a challenge in CO 2 sequestration with enhanced gas recovery (CS-EGR) in shale gas reservoirs. In this study, we focus on the adsorption behaviors of CO 2 and CH 4 on kerogen type IIIA using molecular dynamics (MD) and Grand Canonical Monte Carlo (GCMC) simulations. Simulation results indicated that the difference between the adsorption capacity of CO 2 and CH 4 increased with increase of mole fraction of CO 2 . The adsorption capacity of CO 2 /CH 4 decreased with increase of the water content. Water showed a greater effect on the adsorption of CO 2 than on that of CH 4 . The isosteric heat and adsorption selectivity of CO 2 /CH 4 decreased at low water content and increased with increasing water content. This study provides certain theoretical guiding significance for the application of CS-EGR projects from a microscopic perspective.

“…19 is a standard pattern during nes migration in the porous rocks under brine and CO 2 ow. Recent reports suggest that pressure change during nes intrusion under CO 2 injection contributes to higher decline in the reservoir rock pressure than any other external injection uid (Othman et al 2018b;De Silva et al 2017). For example, Sokama-Neuyam (2017), examined the impacts of nes mobilization during CO 2 injection in sandstone cores.…”

A laboratory based investigation has been conducted on permeability damage and CO2 storage or retention in the lignite core during alternative injection of brine and supercritical carbon dioxide. Moreover, anthracite and bituminous coal beds were focused by the scientific community for effective production and reservoir formation damage study. But, now-a-days, lignite based coal bed methane reservoirs have attracted attention for productive exploitation and formation collapse investigation. Hence, for this purpose, a single component injection two phase (Brine + Supercritical CO2) coreflood test analysis under alternative injections were performed to investigate the occurrence of lignite structural collapse, permeability damage, injectivity decline and CO2 retention as well. The experimental study reveals that, due to gravity segregation there is a high rate of fluid saturation in lignite core and also, moderate level of heat transfer coefficient was also noted. Also, lignite core structural collapse under the brine and supercritical CO2 injection at different velocities resulted in huge volume of coal and kaolinite fines concentration. Kaolinite and coal fines migration resulted in pressure change and permeability decline in lignite core. The suspensions produced were passed to microstructural analysis and it revealed that kaolinite fine particle tends to possess a leaflet geometrical structure, which obstructed the cleats and restricted the fluid flow. Subsequently, hysteresis modelling (Pranesh 2018) was applied to this problem to quantify the amount of CO2 retention in lignite core. Additionally, statistical model, multiple linear regression was applied to this problem to validate the experimental model, which showed good agreement.

“…The permeability decline in subsurface porous media due to the mobilization of clay fines is a problem encountered in several subsurface engineering applications, such as water disposal, oil recovery, aquifer recharge, geothermal energy, and geological CO 2 storage [1][2][3][4][5][6][7]. When freshwater is injected into porous media that initially contains brine and native non-swelling clay, the sudden change in salinity causes the clay fines to detach from the grains and clog pore spaces, resulting in a significant damage in permeability.…”

Permeability damage in subsurface porous media caused by clay mobilization is encountered in many engineering applications, such as geothermal energy, water disposal, oil recovery, and underground CO2 storage. During the freshwater injection into rocks containing brine, the sudden decrease in salinity causes native clay fines to detach and clog pore throats, leading to a significant decline in permeability. The clay fines detach due to weakened net-attractive forces binding them to each other and the grain. Past experiments link this permeability damage on the immediate history of the salinity and the direction of flow. To better understand this phenomenon, we conducted pore-scale simulations of cyclic injection of freshwater and brine into sandstone containing Kaolinite clay. Our simulations establish a link between the clay-fine trajectory and the permeability trend observed by Khilar and Fogler (1983). For a uniform clay size of 3 microns, we observe a permeability decline by two orders of magnitude during freshwater injection with respect to brine injection. Increasing salinity and simultaneously reversing flow direction restores the permeability. The permeability restoration upon reversing the brine flow direction is attributed to the unblocking of pore throats in the reverse direction by the movement of the clay particles along the grain surfaces by the hydrodynamic force and the strong net-attractive force under high salinity.
