The main objective is to assess the following characteristics:
Determine oil quality
Identify source rock type, level of thermal maturity, and nature of any alteration processes
Undertake oil-oil, oil-condensate, and oil-seep correlations
Define reservoir continuity
Conduct oil-source rock correlations
Samples which can be submitted for analysis include:
Subsurface crude oils and condensates/volatile oils
Surface oils, condensates, and seeps
Oil impregnated reservoir rock in subsurface and in outcrops
A typical Analytical Package:
API Gravity
Sulfur content
Pour Point/Wax Content
Whole oil GC, including detailed light hydrocarbons and C15+ n-paraffin and isoprenoid
Liquid chromatographic (LC) separation - complete or partial
Quantitative GC-MS of saturate hydrocarbon fraction (Saturate Biomarkers)
Quantitative GC-MS of aromatic hydrocarbon fraction (Aromatic Biomarkers)
Stable carbon isotope ratios of saturate and aromatic hydrocarbon fractions
Additional Analyses
Viscosity
Saturated hydrocarbon fraction gas chromatography (C10+ GC)
Aromatic hydrocarbon fraction gas chromatography
Whole oil stable carbon isotope composition
Whole oil sulphur isotope composition
Saturate and/or aromatic hydrocarbon fraction deuterium isotope composition
Nickel and vanadium content
Interpretation and Reporting
A detailed interpretive report can be generated and provides an assessment of the source organic matter type and maturity at generation/time of expulsion, depositional environment, evaluation of any alteration processes, and possibly geologic age. If multiple oils and evaluated, oil-oil correlation and reservoir continuity can be assessed.
