Saturation, morphology, and topology of nonwetting phase fluid in bentheimer sandstone; application to geologic sequestration of supercritical CO2

Creator:

Herring, Anna L.

Abstract:

This work examines the impact of a viscosity force parameter, fluid velocity, and a capillary force parameter, interfacial tension, on the saturation, morphology, and topology of NW fluid in Bentheimer sandstone after primary imbibition, drainage, and secondary imbibition. Brine and air (used as a proxy for supercritical CO₂) flow experiments...

An investigation into the pore-scale mechanisms of capillary trapping : application to geologic CO₂ sequestration

Creator:

Herring, Anna L.

Abstract:

Geologic CO₂ sequestration is a climate change mitigation strategy that prevents CO₂ emissions to the atmosphere by capturing CO₂ gasses from large point source emissions streams and then pressurizing and pumping the supercritical-state CO₂ into underground geologic storage reservoirs. Once underground, CO₂ is prevented from buoyant migration to the surface...
