Real time 3D observations of Portland Cement Carbonation at CO2 storage conditions
Depleted oil reservoirs are considered a viable solution to the global challenge of CO2 storage. A key concern is whether the wells can be suitably sealed with cement to hinder the escape of CO2. Under reservoir conditions, CO2 is in its supercritical state, and the high pressures and temperatures...
Salt clogging during supercritical CO2 injection into a downscaled borehole model
Computed X-ray Tomography Study of Carbonate Precipitation in Large Portland Cement Pores
Carbonation of silica cement at high-temperature well conditions
Electrophoresis-induced structural changes at cement-steel interface
Applying positive potential to a steel electrode immersed into a cement changes the packing of cement particles in the vicinity of the electrode surface. The electrophoresis-induced packing enhancement at anode has promising applications in oil & gas and CO2 storage industries since it could be used...
In-situ X-ray tomography study of cement exposed to CO2 saturated brine
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 CO...
Closing of Micro-cavities in Well Cement upon Exposure to CO2 Brine
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 CO...
Synchrotron Study of Cement Hydration: Towards Computed Tomography Analysis of Interfacial Transition Zone
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...
