Summary: This paper reviews the mechanisms that impact CO2 injectivity during CCS projects and evaluates their relevance through numerical models. Lab scale mechanisms such as water vaporization, salt precipitation, and mineral dissolution significantly affect reservoir properties and injectivity. Numerical models are used to quantify these impacts in synthetic and real field cases, considering multiple factors such as brine composition and mineral reaction dissolution. The results highlight the importance of managing injectivity loss and uncertainty in CCS projects.

Summary: This research quantifies the impact of salt precipitation and fines migration on CO2 injectivity through core-flooding experiments. The results indicate a direct correlation between salinity and severity of injectivity alteration, with higher salinity and larger fines size leading to more significant impairment.

Summary: This research investigated the impact of salt precipitation and fines migration on permeability during CO2 injection into saline aquifers through core flooding experiments. The study found that brine salinity has a greater influence on permeability reduction, and the presence of both salt precipitation and fines migration can intensify the permeability reduction up to threefold. The newly developed model showed a good fit with experimental data and was statistically validated.

Summary: This paper presents the design, execution, and results of the initial halite remediation treatment at the Quest CCS facility. Significant injectivity reductions in the CO2 injection wells were observed due to the precipitation of halite caused by the evaporation of water into the dry CO2. The field treatment involved injecting a water-based fluid to dissolve the halite precipitate, and the effectiveness of the treatment was evaluated through skin analysis and injectivity trends.

Summary: Injectivity index is a powerful tool that can be easily calculated from field injection and pressure data, and it is linked to reservoir properties such as permeability. The relationship between injectivity index and the product of reservoir permeability and thickness has been studied, providing valuable insights for estimating pressure buildup and understanding reservoir flowability.

Summary: The coupled process of CO2 downhole temperature cycles and natural CO2/brine drainage-imbibition cycles significantly affects injectivity during large-scale CO2 injection schemes. The relationship between CO2 phase mobility and temperature is complex, with relative permeability playing a marginal role in mobility changes. Field data suggests that the injectivity of CO2 may be optimized by understanding the functional relationship between temperature, CO2/brine cycling, and CO2 phase mobility.

Summary: The salt precipitation behavior was studied in different heterogeneous structures. In the up-down heterogeneous structure, salt precipitates in situ in small pore structure at low CO2 injection rate and in large pore structure at high CO2 injection rate. In the left-right heterogeneous structure, the precipitated salt mainly forms cluster structure and has little impact on injectivity. Selecting injection well in formation with strong heterogeneity can alleviate blockage caused by salt precipitation, and CO2 leakage in fractures can help in self-healing of the fracture for the caprock.

Summary: Most low-carbon scenarios overestimate the role of carbon capture and storage (CCS) in deep decarbonisation, particularly in key regions such as China and India, due to the assumption of abundant CO2 storage. Limited CO2 storage leads to faster emission reductions and greater reliance on renewable energy.

Summary: A viable CO2 storage resource must have sufficient storage capacity, reliable containment efficiency and adequate well injectivity. Deep saline formations stand out in terms of storage capacity and containment efficiency. However, formation brine dry-out and salt precipitation in the near well region could impair CO2 injectivity in deep saline reservoirs, thus reducing their potential for CO2 storage.

Summary: This study investigated the impact of salt precipitation on storage safety in deep saline aquifers through numerical simulations. The results showed that the salinity of the formation water is approximately proportional to the additional pressure buildup at low salinities, but sharply increases above a certain threshold. Additionally, the permeability and CO2 injection rate affect the additional pressure buildup.

Summary: This study estimates the amount of CO2 stored by facilities since 1996 based on publicly available sources and categorizes them into three assurance levels. The storage estimates indicate significant climate relevance comparable to renewable energy emissions impacts. The widely used capture capacity is not a reliable proxy for storage volumes, emphasizing the need for uniform reporting with quality assurance.

Summary: Salt precipitation during CO2 injection into saline aquifers is a significant phenomenon that reduces permeability and injectivity. Capillary pressure drives brine backflow in water-wet systems, leading to more precipitation. We developed an analytical solution considering the effect of capillary pressure, which was validated using numerical simulations. The solution accurately estimated the influence of capillary pressure on injectivity impairment due to salt precipitation.

Summary: This study used intelligent models to forecast the interfacial tension (IFT) in the CO2-brine system, with the random forest (RF) model performing the best. Sensitivity analysis identified the significant impact of pure and non-pure CO2 systems on the predictions. Additionally, the RF model was used to assess the structural trapping capacity of a specific storage location.

Summary: In CO2 storage in multilayered saline aquifer-caprock, fault-induced salt precipitation can prevent CO2 leakage and can be divided into three stages: convection of CO2 and brine, slow migration of brine, and salt precipitation occurring. The factors affecting salt precipitation include injection rate, fault height, injection time interval, fault dip angle, and distance between fault and injection well.

Summary: Salt precipitation has a significant impact on the injectivity of CO2 storage in deep saline aquifers during the drying-out process. Gravity and reservoir heterogeneity play important roles in the behavior of CO2 plumes and storage capacities. Numerical simulations based on the Sleipner project have shown that gravity increases solid saturation at the injection well in a homogeneous model, and the position of the injection well affects the amount of salt precipitation near it. The research suggests a mutual resistance relationship between gravity and heterogeneity in terms of their collective effect on solid saturation. Additionally, the study found that gravity reduces salt deposition in fracture models, while increased heterogeneity suppresses salt precipitates production at low CO2 injection rates and increases it at high CO2 injection rates. This research has important guiding significance for designing site screening and injection schemes to avoid excessive salt precipitation and pressure build-up.

Summary: The study focuses on a mathematical model for probabilistic mineral nucleation and precipitation, utilizing experiments on calcium carbonate synthesis to demonstrate the impact of nucleation events on crystal precipitation. The results indicate that reaction rate plays a crucial role in governing the covering of substrates with nuclei and subsequent solid-phase accumulation. Incorporating probabilistic nucleation is essential for valid predictions in reactive transport processes.
