“…However, the following are additional challenges and gaps that are suggested from this study: During CO 2 injection and storage, formation damage may be associated with the dissolution and precipitations of active minerals, which can plug and block the porous media. As a result, the permeability of the formation is reduced. − However, most studies, especially experimental works, have reported the effect of formation damage/mineral reaction within the short time (months) while the storage of CO 2 can last for several years . In addition, there are slow reaction minerals like feldspar carbonation that may change the rock properties over long periods of time .…”

Carbon capture and storage (CCS) is a climate change mitigation method in which anthropogenic carbon dioxide (CO2) is captured from large point sources and stored in geological formations, in the ocean, or through mineral carbonation. CO2 can be injected and stored for a variety of reasons, including permanent disposal or enhanced oil recovery in certain oil fields. The main objective of this paper is to assess the advances made in CO2 storage projects globally. This study reviews the major companies/businesses that are involved in CCS deployment. The study also presents the alternative for the sequestration of CO2 into the geological formations through existing major projects. It explains their progress, structural and faulting configuration, CO2 transportation and injection, potential CO2 source(s), estimation of the storage capacity, etc. This study also highlights the monitoring programs that are used in different operating projects and the status of active projects. The study suggests that CCS faces further deployment challenges due to the heterogeneity and complexity of rock formations, high cost of deployment, possibility of formation damage during injection and potential for migration and leakage of CO2. Additionally, inappropriate strategy for CO2 injection may lead to wellbore integrity problems, formation of hydrates, and inadequate pressure control. More researchparticularly, geological evaluation before injection and storageis apparently needed.

“…Also, Adebayo et al reported that, when CO 2 was injected, there was an alteration in grain size as a result of the chemical reaction, which affected the rock grains, and the results are presented in Figure . However, the grain size change contributed to the solubility of grains and the development of new pores or the formation of macropores as a result of the joining of micro- and macropores . Furthermore, the change in the grain size can be observed as a result of the closure of micropores or pore throats through precipitation.…”

“…119 Badrouchi et al experimented to investigate the pore size distribution before and after CO 2 injection using two types of formation samples [Middle Bakken (MB) and two Three Forks (TF)]. 67 They employed the nuclear magnetic resonance (NMR) to provide detailed results and concluded that the effective porosity decreased from 5.3 to 3.8% for MB samples, while for TF samples, the effective porosity was reduced from 7.6 to 6.3%, and the distribution of the pore size was presented in Figure 9 for detailed analysis. However, Figure 9 suggests that the pore distributions from all wells have shown a considerable decline in their distribution to the formation after injection as a result of dissolved CO 2 to the formation rock with active minerals, in which formation damage was experienced.…”

Some of the challenges presented with these reports were geo-mechanical and geochemical, such as dissolution and precipitations − of reactive minerals that can change the injectivity of CO 2 and block pores during precipitation, consequently reducing the permeability of the formation. , …”

Review on Experimental Investigation into Formation Damage during Geologic Carbon Sequestration: Advances and Outlook

Carbon capture and storage has been identified as an important and viable technology for climate change mitigation. The technology allows CO 2 generated from largescale sources, such as power plants and other heavy industries, to be captured and stored in deep geological formations. However, when CO 2 is stored in geological formations, there are possibilities of formation damage, which may reduce injectivity and storage capacity. In this study, formation damage during CO 2 injection and storage is reviewed through different experimental studies. The study has shown that the interaction between CO 2 , formation water, and rock minerals often results in mineral dissolution and precipitation, which affect reservoir permeability and porosity, which could possibly cause formation damage, compromising the reservoir storage capacity. This study also reveals that formation damage could be caused by the precipitation of sulfate scales, salt, and carbonate minerals. Additionally, in several studies, rock minerals were observed to dissolve and create free particles that were transported to occupy pore spaces along the fluid flow path, reducing permeability and impacting CO 2 injectivity and storage. It is worth noting that the reviewed experiments present short-term effects of formation damage on geological formations, while in reality, CO 2 storage is a long-term project, thus eliciting the need for more studies in that regard.
