Computed tomography (CT) is a useful sample characterization and analysis technique to
better understand complicated reactive transport processes in geologic CO 2 utilization and …

Microbially-induced calcium carbonate precipitation (MICP) is an emerging biotechnology
for wellbore integrity applications including sealing defects in wellbore cement and …

A significant concern in oil and gas well construction is well integrity. The inability to obtain
proper zonal isolation during cementation can lead to severe consequences threatening the …

Fracture networks inside the caprock for CO2 storage reservoirs may serve as leakage
pathways. Fluid flow through fractured caprocks and bypass conduits, however, can be …

Portland cement hydration is a chemically sensitive process impacted by temperature,
amount of water and the presence of any potential contaminants. Drilling fluids …

In HPHT gas wells, thermal expansion annulus pressure might threaten the mechanical
integrity of the cement sheath. To analyze the effect of the thermal expansion annulus …

Well-cementing (cementation) is an influential stage of a wellbore completion, as the cement
sheath is responsible for providing a complete zonal isolation. Therefore, it is of utmost …

Leakages of greenhouse gases, such as methane and carbon dioxide from wells, may have
considerable environmental consequences. Although much emphasis is currently put on …

This study presents a novel laboratory-scale experimental/numerical approach that
contributes to our understanding of micro-annular flow paths in cement-caprock interfaces …

Concerns about leakage exist when storing fluids like CO 2 or natural gas in the subsurface
given their potential to damage functional groundwater aquifers or be emitted to the …
