AQUIFER REMEDIATION

 

The research described in this NSF CAREER project is emphasized as a critical area of Science and Technology under the University of Wyoming Plan and the Wyoming NSF EPSCoR program. The objective is to investigate the effect of mineralogy and wettability on the transport and remediation of NAPLs in heterogeneous rocks. The project is designed to conduct innovative high-impact research activities that will be disseminated into effective learning tools. It provides great opportunities to train students through multi-facet research and education in STEM-related areas using state-of-the-art imaging and modeling techniques.

X-ray computed microtomography is used: (i) to generate high-resolution maps of pore space topology and mineralogy in rock samples from which network models are constructed, and (ii) to perform well-characterized in-situ flow experiments to measure fluid occupancy and the effect of chemical additives on NAPL remediation in the same rocks. The impact of NAPLs on wettability alteration is examined using a state-of-the-art interfacial tension and contact angle apparatus. A pore-scale network model is also used for two-phase flow simulations and rigorously validated against experimental data to predict the performance of surfactant-enhanced remediation methods. The model uses most realistic representations of pore-space topology and explicitly accounts for heterogeneities in rock mineralogy and wettability on a pore-by-pore basis to faithfully predict the impact of wettability alteration on NAPL displacement mechanisms in heterogeneous rocks.  

Results from this investigation are expected to advance knowledge and understanding in industrial applications such as management and optimization of water resources, remediation of contaminated aquifers, underground storage of flue gases, and improved oil recovery from conventional and unconventional resources.
