“…Evidence of fines migration has been observed in Berea sandstones as a result of core flooding with scCO 2 -saturated brine (Ge et al, 2020;Othman et al, 2019); a companion study (Zhang et al, 2020) indicated that the mineral phases kaolinite, chlorite, and muscovite exhibited physical and/or chemical changes after exposure to scCO 2 -saturated brine and were most likely to be mobilized (in contrast to quartz and microcline, a potassium-rich feldspar, which showed no changes upon exposure). Ge et al (2020) and Zhang et al (2020) suggest that a primary impact of fines migration is the mobilization of fines and subsequent blockage of pore throats, leading to reduced permeability. In a more recent study, Ge et al (2022) also found that fines migration increased residual saturation of scCO 2 ; the authors attribute this effect also to pore throat blockage.…”

Almost all scenarios that limit climate-change-caused temperature rise to ≤2°C rely on large-scale geologic sequestration to redirect carbon dioxide (CO 2 ) emissions away from the atmosphere and instead into underground storage (IPCC, 2014(IPCC, , 2019. Geologic sequestration is being considered both as a way to prevent carbon emissions from large point source polluters (e.g., fossil fuel energy production, cement manufacturers), and also as a potential negative emissions technology when coupled with bioenergy with carbon capture and storage, or direct air capture (Bui et al., 2018;IEA, 2020;IPCC, 2005IPCC, , 2019. The short-term (i.e., order of decades) security of a geologic sequestration operation in a sedimentary formation relies on two physical mechanisms: (a) the presence of a sound impermeable caprock to enable "structural" trapping of the relatively buoyant CO 2 plume below the caprock (Shukla et al., 2010; Song & Zhang, 2013), and (b) the interfacial interactions between rock-CO 2 -resident brine which break off small bubbles of disconnected CO 2 within the pore structure of the rock formation, termed "capillary" or "residual" trapping (Abidoye

“…Consequently, based on Eq. ( 26), quartz, which is homogeneous with a smaller point of zero charge pH than sandstone and must show water wetness, which has been experimentally demonstrated (Kaveh et al, 2014;Zhang et al, 2000). The dependence of water contact angle on hydroxyl functional groups (Chen et al, 2015) of a substrate is further prove that the surface of an aggregate of minerals (rock) must have surface functional group heterogeneity and must have contact angle different from that of a homogenous mineral and this has been theoretically established in this paper..…”

“…For instance, the experimental results Kaveh et al (2014) show that the wettability of Bentheimer sandstone/water system, originates from differences in the surface charges of quartz and Bentheimer sandstone (Kaveh et al, 2014), which must be due to differences in the surface chemistry of the two substrates, which reflect the point of zero charge pH. Zhang et a., (2000) have shown differences in carbon dioxide contact angle for Berea and Obernkirchener sandstones due to differences in rock mineralogy, which affects surface chemistry. They further showed that quartz demonstrated strong water wetness compared to sandstone.…”

In colloidal science and bioelectrostatics, the linear Poisson Boltzmann Equation (LPBE) has been used extensively for the calculation of potential and surface charge density. Its fundamental assumption rests on the premises of low surface potential. In the geological sequestration of carbon dioxide in saline aquifers, very low pH conditions coupled with adsorption induced reduction of surface charge density result in low pH conditions that fit into the LPB theory. In this work, the Gouy-Chapman model of the electrical double layer has been employed in addition to the LPBE theory to develop a contact angle model that is a second-degree polynomial in pH. Our model contains the point of zero charge pH of solid surface. To render the model applicable to heterogeneous surfaces, we have further developed a model for the effective value of the point of zero charge pH. The point of zero charge pH model when integrated into our model enabled us to determine the point of zero charge pH of sandstone, quartz and mica using literature based experimental data. In this regard, a literature based thermodynamic model was used to calculate carbon dioxide solubility and pH of aqueous solution. Values of point of zero charge pH determined in this paper agree with reported ones. The novelty of our work stems from the fact that we have used the LPB theory in the context of interfacial science completely different from the classical approach, where the focus is on interparticle electrostatics involving colloidal stabilization.

“…In the formation of water, CO 2 , and pore surface, CO 2 can make mica and quartz surfaces with strong water wettability behave as neutral wetting. This phenomenon is significantly affected by mineral concentration [235]. Although it is not apparent, the boundary slip exists in the oil phase displaced by CO 2 in the inorganic pores.…”

The difficulty of deploying remaining oil from unconventional reservoirs and the increasing CO2 emissions has prompted researchers to delve into carbon emissions through Carbon Capture, Utilization, and Storage (CCUS) technologies. Under the confinement of nanopore in unconventional formation, CO2 and hydrocarbon molecules show different density distribution from in the bulk phase, which leads to a unique phase state and interface behavior that affects fluid migration. At the same time, mineral reactions, asphaltene deposition, and CO2 pressurization will cause the change of porous media geometry, which will affect the multiphase flow. This review highlights the physical and chemical effects of CO2 injection into unconventional reservoirs containing a large number of micro-nanopores. The interactions between CO2 and in situ fluids and the resulting unique fluid phase behavior, gas-liquid equilibrium calculation, CO2 adsorption/desorption, interfacial tension, and minimum miscible pressure (MMP) are reviewed. The pore structure changes and stress distribution caused by the interactions between CO2, in situ fluids, and rock surface are discussed. The experimental and theoretical approaches of these fluid-fluid and fluid-solid reactions are summarized. Besides, deficiencies in the application and safety assessment of CCUS in unconventional reservoirs are described, which will help improve the design and operation of CCUS.
