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. |
