Oil Analyses

What you can get from geochemical analysis of crude oil:

• Organic Facies of Source Rock (Genetic type and petroleum system)

- Marine, lacustrine, or terrigenous organic matter
- Anoxic or suboxic depositional environment
- Carbonate or shale lithology

• Age of Source Rock

- Tertiary, Mesozoic, Ordovician, etc.

• Maturity (time of expulsion should relate to kinetics of source rock kerogen)

- Should relate to kinetics of source rock kerogen

• Single or Multiple Source Rocks

- Two or more genetic types
- Two or more expulsion maturities
- Two or more altered types

• Alteration Effects

- Biodegradation
- Water washing
- Gas stripping
- Thermal

• Data (oil-rock correlation, oil-oil correlation, and oil-condensate correlation)

• Techniques Most Often Used

- Whole oil gas chromatography (C2 - C40)
- High resolution C7 GC
- Liquid chromatography (saturates, aromatics, NSO's, asphaltenes)
- Saturate and aromatic Biomarkers (GC/MS)
- Saturate and aromatic carbon isotopes

• Supporting Techniques

- Aromatic GC
- Ni and V content
- Sulfur isotopes
- Physical properties (API gravity, etc.)
- Saturate GC/MS/MS
- Compound specific isotopes GC/IRMS
- High temperature gc (C20 - C60)
- Pyrolysis of asphaltenes

Oils and condensates can also be analyzed with special high resolution GC for reservoir studies.
