Avoiding Damage of CO2 Injection Wells Caused by Temperature Variations

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1487346

Well integrity is a prerequisite for safe geological storage of CO2. Both active and abandoned wells are man-made channels between the storage reservoir and the atmosphere that can become leakage paths over time. The CO2 injection wells are of special concern, as they are exposed to low temperatures...

Porosity Changes in Mud-affected Rock and Cement upon Reaction with CO2

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1487349

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 we...

Assessment of Thermal Stress on Well Integrity as a Function of Size and Material Properties

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1487355

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...

Aliso Canyon Leakage as an Analogue for Worst Case CO2 Leakage and Quantification of Acceptable Storage Loss

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1487400

The Aliso Canyon gas well leakage is used as an analogue to study a possible accident from a CO2 storage site. Because the blowout is the second largest in USA, it can be used as a worst-case blowout analogue for a possible CO2 blowout from an underground CO2 storage. Reservoir modelling and well mo...

Large Scale Tertiary CO2 EOR in Mature Water Flooded Norwegian Oil Fields

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1487399

A technical-economical model for a large-scale infrastructure combining CO2 EOR and aquifer storage has been used to construct a scenario including 23 Norwegian Continental Shelf oil fields that have been identified as potential candidates for CO2 flooding. In the injection scenario, 70 million tonn...

Synchrotron Study of Cement Hydration: Towards Computed Tomography Analysis of Interfacial Transition Zone

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1487402

The quality of bonding between cement and steel in wells is controlled by the interfacial transition zone (ITZ). Micro-computed X-ray tomography (μ-CT) imaging with synchrotron radiation was used in the current paper to study the development of ITZ at the early stages of hydration. The experiments h...

Closing of Micro-cavities in Well Cement upon Exposure to CO2 Brine

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1487407

Long-lasting cement plugging of wells is crucial for successful CO2 storage in underground reservoirs. It requires a profoundly improved understanding of the behavior of fractured cement under realistic subsurface conditions including elevated temperature, high pressure and the presence of CO2 satur...

In-situ X-ray tomography study of cement exposed to CO2 saturated brine

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1483590

For successful CO2 storage in underground reservoirs, the potential problem of CO2 leakage needs to be addressed. A profoundly improved understanding of the behavior of fractured cement under realistic subsurface conditions including elevated temperature, high pressure and the presence of CO2 satura...
