: Ansong GENG (耿安松)
Position: Research Professor, Member of International Eurasian Academy of Sciences
Department: State Key Laboratory of Organic Geochemistry


My research is focused on the petroleum geochemistry, especially on the method and indicators of resource assessment of oil & gas, dealing with comprehensive identification of coal gas, petroleum migration, hydrocarbon generation of special type of organic matter, geochemistry of solid bitumens and aspheltenes, expulsion and migration of gas, kinetics of hydrocarbon generation and application of hydropyrolysis, using a combination of fieldwork and geochemistry, particularly molecular organic geochemistry and stable isotope geochemistry as well as experimental modelling.

My current projects include tracing the process of hydrocarbon generation in marine strata in southern China, research on the assessment system of hydrocarbon generation of deep high mature source rocks, novel techniques for oil-source correlation of high evolutional marine strata etc..

I currently serve as an editor board member of Chinese Science Bulletin.
