Carbonated Water Injection for Enhanced Oil Recovery and CO2 Geosequestration in Different CO2 Repositories: A Review of Physicochemical Processes and Recent Advances

abstract: With increasing global energy demand and the urgency to reduce carbon emissions, carbonated water injection has been proposed to tackle these pressing concerns. Carbonated water injection (CWI) in oil formations enhances oil production to support the global energy mix and tackle the issues of energy security, energy equity, and environmental sustainability. However, CWI in oil reservoirs and saline aquifers initiates multiple chemical reactions that promote carbon mineralization, cause formation damage problems, sea-bed subsidence, and reservoir compaction, increase the injection pressure requirement, and consequently affect the practicality of CWI for enhanced oil recovery (EOR) and CO2 storage. We therefore extensively reviewed the performance of CWI for EOR and CO2 storage and the implications of these interactions on EOR and CO2 storage. The analysis covered recent advancements in CWI, including its synergy with various EOR techniques where it was identified that combining CWI with surfactants, polymers, mutual solvents, and nanomaterials significantly improved oil recovery in tight formations (37-65) compared to standalone CWI (35-36), but the CO2 storage potential of the hybrid technique remains unexplored. Additionally, the complex geochemical interactions that occur during CWI, the influencing variables of these interactions, and their consequence on EOR and CO2 storage were discussed. The rigorous analysis revealed that the existing literature lacks consensus on the effects of CWI on pore structure. Geochemical interactions caused a â��12 to +95 porosity change and a â��96 to +417 alteration in permeability. Primarily, economic challenges including CO2 capture and transportation costs, carbonated water preparation, etc., and corrosion concerns hinder the large-scale implementation of CWI. Notwithstanding, the findings from the life cycle assessment of CWI suggested the economic viability of CWI and highlighted the importance of adopting the innovative CWI t…
