A comprehensive review of remediation strategies for mitigating salt precipitation and enhancing CO injectivity during CO injection into saline aquifers.

Geological CO sequestration is a proven method for mitigating climate change by reducing atmospheric CO levels. However, CO injection often induces salt precipitation, leading to decreased formation permeability, which in turn limits CO injectivity and storage capacity. Conventional approaches, such as freshwater and low-salinity water injection, have been employed to mitigate salt precipitation.
