Salt clogging has been recognized as an important factor for injectivity impairment in the CO₂ injection wells. While only a small amount of field experience with salt clogging has been reported to date, a large number of experimental and numerical studies have been published on the topics of...

Well integrity is crucially dependent on the bonding quality between cement and rock. Several studies have been made of this in the past, but none have taken into account that the drilled rock can be fractured and damaged during drilling. Especially a caprock fractured in the near-well zone can...

Wellbore integrity is critical to long term carbon storage. During CO₂ injection, changes in temperature may result in large stress variations that can damage the well, threatening its integrity. The different materials comprising the wellbore and near-wellbore environment (namely the casing, cement...

Leakage from CO₂ storage reservoirs is a threat towards safe and cost-efficient Carbon Capture and Storage (CCS), and active and abandoned wells have been identified as the most probable leakage paths. This underlines the importance of ensuring well integrity throughout the entire life-cycle of a...
