  • Linking pore-scale interfacial curvature to column-scale capillary pressure

    Creator:
    Armstrong, Ryan T., Porter, Mark L., and Wildenschild, Dorthe
    Abstract:
    Synchrotron-based tomographic datasets of oil–water drainage and imbibition cycles have been analyzed to quantify phase saturations and interfacial curvature as well as connected and disconnected fluid configurations. This allows for close observation of the drainage and imbibition processes, assessment of equilibrium states, and studying the effects of fluid phase disconnection...

  • Microbial enhanced oil recovery : a pore-scale investigation of interfacial interactions

    Creator:
    Armstrong, Ryan T.
    Abstract:
    Current oil production technologies recover only about one‐third to one‐half of the oil originally present in an oil reservoir. Given current oil prices, even a modest increase in oil recovery efficiency is fiscally attractive. One novel approach to increase oil recovery efficiency is a process called microbial enhanced oil recovery...
