“…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].…”

“…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).…”
