Earth Sciences Division Staff: Tianfu Xu
Tianfu Xu is a Career Staff Scientist at the Lawrence Berkeley National Laboratory (LBNL), which he joined in 1996 initially as post-doctoral fellow. He received a bachelor’s degree in 1984 from Jilin University of China, an M.S. degree in 1993 from Delft University of Technology of The Netherlands, and a Ph.D. in 1996 from University of La Coruña, Spain. For the last 16 years, Tianfu has been working on developing new approaches to modeling multiphase non-isothermal fluid flow and reactive transport in unsaturated and saturated porous media and fractured rock systems. He is the chief developer of LBNL’s multi-phase non-isothermal reactive flow and chemical transport simulator TOUGHREACT. The program is among the most frequently requested codes in the library of the Department of Energy's Software Center, and is widely used nationally and internationally for CO2 geological sequestration, geothermal energy development, nuclear waste disposal, environmental remediation, and increasingly for petroleum applications. Tianfu has authored and co-authored about 40 peer-reviewed journal papers. His papers have been cited by other researchers more than 360 times (SCI citation).
- Developing new approaches for modeling multiphase non-isothermal fluid flow and geochemical transport in unsaturated and saturated porous media and fractured rock systems.
- Developing novel conceptual models integrating geologic, thermal, geochemical, microbiological and hydrologic data.
- Incorporating conceptual models into numerical modeling codes for the evaluation of subsurface coupled processes.
- CO2 geological sequestration: Fate and transport of injected CO2 in storage reservoirs, mineral trapping, caprock and cement alterations due to CO2 intrusion, and the impact of CO2 leakage on groundwater quality.
- Natural groundwater quality and environmental remediation: Acidic mine drainage remediation, organic matter decomposition, and effective environmental remediation of groundwater contamination.
- Geothermal energy development: Formation scaling due to water injection, optimization of injection water chemistry, chemical stimulation for enhanced geothermal system (EGS), use of CO2 as working fluid for EGS (CO2-EGS), controlling and mineral dissolution and precipitation in the reservoir.
- Nuclear waste geological disposal: Radionuclide reactive transport, coupled thermo-hydro-chemical (THC) processes, steel canister corrosion and H2 gas generation.
- Reactive transport applications to petroleum processes: Porosity evolution of carbonate diagenesis, evaluation of deep injection of H2S separated from natural gas reservoirs, and optimization of injection water chemistry to avoid formation damage due to waterflooding.
