Extensive experience in petroleum geology/geochemistry, including evaluating petroleum systems, as well as evaluation of hydrocarbon source potential of sedimentary basins; evaluating and assessing the unconventional shale gas plays; evaluating and interpreting the biological marker and stable isotope data and integrating them to the petroleum system assessment of sedimentary basins; Reservoir Oil Fingerprinting (ROF) and reservoir continuity studies.

Applying geological and geochemical (including biomarker fingerprints and stable isotopic compositions) to identify and characterize source rocks, crude oils and natural bitumen, as well as oil-to-oil and oil-to-source rock correlation. Setting up and managing petroleum geochemical laboratories.
