• Identify the presence of migrated HCs in sediments, cuttings, cores, and fluid inclusions. 
• Evaluate the origin (source facies or age), maturity, level of alteration (biodegradation or contamination) of HC fluids, assess oil-oil, oil-source rock correlation; petroleum systems analysis
• Analyze pressure-volume-temperature-composition (PVTX) properties of fluids and integrate with available geochemical data to understand controls on fluid properties; pre-drill prediction of commodities and fluid property.
• Integrate Exploration geochemistry data for basin modelling, petroleum system analysis, and play element assessment
• Evaluate static and dynamic reservoir fluid connectivity
• Model production allocation of oils from conventional and unconventional assets 
• Integrate production geochemistry data with reservoir geo models, 4D seismic, production surveillance, hydraulic fracture models, well and reservoir engineering 
• Model rock-fluid and fluid-fluid chemical interactions for carbon sequestration
• QA/QC external and internal analytical data, vendors and partners’ reports
• Improve PG workflow, capability, and competitiveness including but not limited to analytical geochemistry, molecular geochemistry, geochemical modelling, database digitization, and workflow automation 
• Evaluate emerging techniques (internal and external) and applications across the value chain
• Mentor junior professionals
