Abstract

Geochemical characterization of eleven (11) oil samples has been carried out; using diagnostic biomarker parameters related to thermal maturity, organic matter source, age and depositional environment. Oleanane was only found in the Nigerian oil, serving as a primary feature in distinguishing it from other oils. All the oil samples appeared to have mixed organic matter input with samples of the same region closely related to each other based on the parameters measured. Biodegradation of some of the samples may have contributed to some of the observed variabilities.

 

Key words: Biomarker, Oleanane, biodegradation, thermal maturity.
