Name: Zewen LIAO (廖泽文)
Position: Research Professor
Department: State Key Laboratory of Organic Geochemistry


My work is carried on mainly in the field of petroleum geochemistry, especially on the geomacromolecules such as kerogens, asphaltenes and bitumens for which to study their adsorption/occlusion properties and the related geochemical applications in oil reservoirs. Recently the quantitative evaluation of the mixed oil reservoirs is also one of my interests, and currently I am working in the area of biogeochemistry associated with the source rocks of the oil reservoirs by applying the methods such as compound specific isotope ratios, biomarker analyses.

My current projects are mainly involved in the work on the geomacromolecules, especially associated with the geochemistry of oil reservoirs from Tarim Basin, NW China, and on the geochemical study of the bitumens from Sichuan Basin.
