“…After some of particles detached, the initial particle concentration in pore space could simply divided into two groups: (i) the retained particles defined by the critical retention concentration function (𝜎 𝑐𝑟 ) and (ii) the rest of particles flowing along pore channel which is later strained (𝜎 𝑠 ) or plugged in porous media and causing permeability decline. 27 It is assumed that all particles detached will be later strained in porous media, although in fact detached particles might be not all strained but some suspended or mobilized further. This can form a simple relation as:…”

“…In order to mitigate this phenomenon, the authors suggested fresh water pre-flushing prior to scCO2 injection. This suggestion is doubtful, it is well know that injection of fresh water in sandstone reservoir can cause severe damage due to fines migration [19,20]. Other researchers also documented similar results utilizing different experimental methodologies and concluded that besides salinity, there other parameter that can direct affect the salt precipitation [13,14,21,22].…”

CO2 emission has increased significantly in the past 50 years and it has become a real threat to the environment. One of the alternatives to decrease CO2 emission is storage it into aquifer or depleted oil reservoirs. During CO2 injection into reservoirs, industries have faced numerous problems. The main problems mentioned in the literature are salt precipitation and cement degradation. In this paper, we propose a methodology to select the most relevant works related to the previous mentioned problems. Afterwards, we prepare a brief literature review including the main physical mechanisms, phenomena, and finds regarding to salt precipitation and cement degradation. Finally, we conclude the paper showing the potential technological opportunities to be developed.

“…This sharp fall in the produced uid recovery rate is due to structural collapse and coal nes production, and mainly, kaolinite clay nes migration. Furthermore, nes comprising porous rocks undergo a colloidal-suspension ows under external uid injection, especially water ow and this causes nes to detach from the rock and nally migrate and entrap in the pore-throats and cleats areas of rock, where the damaging the permeability and declining the recovery of the injected uid (Chequer et al 2018;Russell et al 2014;Guo et al 2015;Kalantariasl et al 2014). Moreover, reduction in the surface energy and pore-straining in the porous rocks gradually lead to injectivity decline (Kanimozhi et al 2018;Gomes et al 2017).…”

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.
