A Study of Transport of Micellar Fluids in Porous Media
… a constant nominal capillary number of 10^-2. Residual phase saturation (capillary desaturation curve) and endpoint relative permeability have also been measured for three-phase micellar fluids as a function of capillary number in a Berea core. Continuous and slug displacements of both …

Delay of Spring Snowmelt due to Storm-Induced Changes in Snowpack, Columbia River Headwaters, Western Montana, USA
… pore space must be filled with liquid water to residual saturation. We investigate the role of these two processes in delaying spring snowmelt following storm episodes in western Montana through analysis of ~10 years of historical snowpack and air temperature data for 33 stations in the Columbia …

Pore scale study of crude oil distribution and interfacial processes in unconsolidated porous media: an application of synchrotron x-ray microtomography
… with three types of sand, were established with residual saturations of light, heavy, and extra-heavy crude oil fractions, respectively. These columns were then flooded with anionic surfactant solution in various episodes. Synchrotron X-ray microtomography (SXM) was used to obtain high-resolution …

Characterization of tight and shale unconventional gas reservoirs using low field NMR
… methods of measuring porosity, permeability, residual saturations, and excess and absolute adsorption isotherms. The experiments were conducted on different porous media such as shale cores, tight sand cores, activated carbon, and sandpacks at pressures up to 7 MPa. In this thesis, for 150 …

Localization with the EnKF for the Automatic History Matching of the SAGD Processes
… As the transition zone could be identified by saturation and temperature distribution, temperaturebased and saturation-based localization were proposed for automatic history matching of SAGD processes. The regions of the localization function were determined through covariance analysis by using …

Computational Tools for Improved Analysis and Assessment of Groundwater Remediation Sites
… is aggressively treated or removed and the residual groundwater plume depletes due to natural processes in the subsurface. The USEPA requires long-term performance monitoring of groundwater at MNA sites over the remediation timeframe, which often takes decades to complete. Presently, …

Solubilization of volatile organic compounds in edible nonionic surfactants
… compounds and the inability to dissolve residual saturation are the major limiting factors for traditional pump-and-treat remediation. Different chemicals have been used to enhance traditional pump-and-treat remediation. Surfactant enhanced subsurface remediation is identified as a …

Micromechanical study of two-phase flow during air sparging
… properties of air water two-phase flow including residual saturation, changing rate of water/air saturation, air and water spatial distribution, dynamic phase transitions, nonwetting fractional flow, air and water relative permeability and capillary pressure curve were systematically investigated. …

Processes controlling the behavior of LNAPLs at groundwater surface water interfaces
… of LNAPL in all three zones * Modeling fluid saturations versus height in a porous media using a force balance is more complex than two forces and requires further research A common theme with current solutions for LNAPLs at GSIs is their failure with time. Failure is defined as the …
