Engineering problems in the chemical sciences range from bench scale to pilot plant.
- Established the Geology and Geochemistry Research team to determine the feasibility/risk of long-term geologic storage of carbon. Current focus areas include (1) wellbore integrity (performance of cement, steel, and rock composite systems), (2) rock-brine-supercritical CO2 flow and reaction in porous and fractured media, (3) groundwater impacts related to CO2 leakage, and (4) field carbon sequestration studies (natural analog and controlled experiments).
- Worked with the University of Wyoming to explore the feasibility of carbon capture, utilization, and storage by using industrial-scale (1 km3 supercritical CO2) numerical simulations of geological CO2 storage within the Rock Springs Uplift in Wyoming. This work helped predict the CO2 storage capacity in the Weber sandstone at the Rock Springs Uplift and helped evaluate uncertainty in well injectivity and leakage through cap-rocks.
- Worked with the University of Utah to determine the potential for using waster and CO2 as a geothermal fluid. The collaborators used a massively parallel three-dimensional reservoir simulator known as PFLOTRAN to simulate liquid flow through geologic formations and chemical interactions with the host rock.
- Developed and implemented couple heat, flow, and deformation simulations for Fenton Hill, Coso, Hijiori, and other sites around the world. Developed coupled rock mechanics and flow capability to assess and design reservoir development. We also continue to model complex geochemical interactions coupled with fluid flow, if warranted by conditions at the site.
- Apply gas chromatography to separate gas mixtures and characterize the gases qualitatively and quantitatively. This method uses chromatographic columns to separate gas mixtures into individual components and then detects the components with a variety of detectors. The methods could use tradition gas chromatographs with packed or capillary columns (analysis time on the order of minutes) or micro gas chromatographs (analysis time on the order of seconds).
- Developed the FEHM computer code originally to simulate geothermal and hot dry rock reservoirs. Today, scientists use FEHM to simulate groundwater and contaminant flow, as well as transport in deep and shallow, fractured and unfractured porous media throughout the Department of Energy Complex. FEHM has proved to be a valuable asset on a variety of projects of national interest, including Environmental Remediation of the Nevada Test Site, the Los Alamos Groundwater Protection Program, geologic CO2 sequestration, Enhanced Geothermal Energy programs, oil and gas production, nuclear waste isolation, and Arctic permafrost.
- Developed HTS HGMS (High-Temperature Superconducting, High-Gradient Magnetic Separation), which removes pollutants from solids, liquids, and gases. Because it is a physical separation process, no additional chemicals are required, which means the system introduces no pollution of its own. This technology enables high-gradient magnetic separation to be used in the field to clean up contaminated soil and water.
- Investigating carbon capture, utilization, and storage as a way to transition from fossil fuel to sustainable energy. One of the most promising and practical methods is geological CO2 storage in saline aquifers. Projects involving this technology are performed in collaboration with countries such as Canada, Australia, and China.
- Supercritical Fluids Experimental Facility: This facility engages in basic and applied research in the use of supercritical fluids in industrial and defense-related processes. Areas of interest include precision cleaning/degreasing, analytical methods development, extraction of contaminants and solvents, chemical and polymer synthesis, and chemical waste destruction.
