ABSTRACT: A Critical Assessment of the Application of Aromatic Hydrocarbons to Source and Maturity Studies on Oils and Associated Source Rocks
BOREHAM, CHRISTOPHER J., TREVOR G. POWELL, and ROGER E. SUMMONS, Bureau of Mineral Resources, Canberra, Australian Capital Territory, Australia
Two- and three-ringed aromatic hydrocarbons have been used in the qualitative assessment of thermal history in sediments and oils for over a decade. Although a variety of chemical maturation parameters have been coined, source influences can preclude their general applicability. This has limited the acceptance by the general petroleum community to the benefits of aromatic hydrocarbon analysis. Recently, exploitation of these specific and nonspecific source inputs has refocused attention to an examination of the two- and three-ringed aromatic biomarkers.
This presentation will discuss the strengths and pitfalls in the application of aromatic hydrocarbons for assessing thermal maturities in type I, II, and III organic matter and in their use in oil-source rock correlation studies. Examples will be cited with reference to Australian samples.
