Professional
Work Experience
A.
Present Position: Research Associate/Organic Chemist, Bureau of Economic
Geology, The University of Texas at Austin (April 2008
– Present).
As
PI or Co-PI for several research projects financially supported by ExxonMobil,
Shell, ConocoPhillips, and also as one of key researchers of MSRL (Mudrock System Research Laboratories), my research focus is
on shale gas and tight oil geochemical characterization and integration with
geological elements (lithology, geological facies)
and pore characterization to evaluate gas and oil storage, petroleum generation
and migration, oil saturation and fluid properties. I also setup a new gas
geochemistry laboratory in the Bureau with the Startup Funds provided by
Jackson School of Geosciences.
B.
Laboratory Manager and Research Geochemist, Power, Environmental & Energy
Research Center (PEER center)
Chemistry and Chemical Engineering Division, California
Institute of Technology, Pasadena, CA (March 2007 – April 2008).
Responsible for geological interpretation of petroleum and
natural gas origin and accumulation in sedimentary basins worldwide;
research-project, annual-report, final-report, and proposal writing; and
effective management of PEER chemistry laboratories.
C.
Postdoctoral Scholar, Chemistry and Chemical Engineering Division, California
Institute of Technology, Pasadena, CA
Chemistry and Chemical Engineering Division, California
Institute of Technology, Pasadena, CA (September 2001 – February 2007).
Focus:
integrated geological and geochemical tools for petroleum reserves assessment,
geochemical methods for petroleum and natural gas exploration, CO2 origin and
accumulation in sedimentary basins, H2S and CO2 risk prediction from TSR prior
to drilling.
D.
Visiting
Scientist, Institute of Petroleum and Organic Geochemistry of Juelich Research Center, Germany (January 1999 – July
1999).
Quantitative investigation of cap-rock sealing properties of oil
and gas for providing important parameters of basin modeling; conduction of gas
migration in diffusion to evaluate extent of carbon-isotope fractionation of
methane on experimental and geological time scales; establishment of
mathematical procedure by which the extent of isotopic fractionation can be
estimated on the geological time scale.
E.
Professor
of Geochemistry, State Key Laboratory of Gas Geochemistry, Lanzhou Institute of
Geology, Chinese Academy of Sciences (CAS) (November 1998 – August 2001).
As PI or Co-PI, focused on integrating geological observations and
geochemistry of natural gas and sources;established
a method of composition analysis for oil/gas inclusions trapped in reservoirs
by means of ultraviolet laser ablation; reconstructed oil- or gas-filling
history in reservoirs and identified oil/gas-filling stages of the trap by
combining fluid-inclusion microthermometry in the
Sichuan sedimentary basin, China; conducted field and laboratory measurement of
soil gas (including free phase and absorbed phase), soil secondary carbonate,
and mercury; established relationship between enrichment of soil secondary
carbonate and microseepage hydrocarbon from deep
reservoirs; proposed new mechanism of mineralization in soils resulting from
hydrocarbon microseepage;built classification of
natural gas origins in a depression on the basis of natural gas geochemistry;
evaluated a prospective target for unconventional natural gas accumulation
within the depression; conducted N2, CO2, Hg gas geochemistry and He and Ar noble gas geochemistry in main gas fields of China;
discovered close relationship between helium and argon isotopes and fault
activity and volcanic activity; developed geochemical criteria to identify
mantle-derived CO2.
