ABSTRACT

Asphaltenes (isolated by preparative TLC) from Potiguar Basin (Brazil) crude oils were submitted to mild oxidation to disrupt their structure, releasing the occluded oil. The released hydrocarbons were compared with those from the original crude oil, in order to provide an additional insight regarding composition in biomarkers and depositional paleoenvironment. It was possible to suggest that the oil samples present low thermal evolution, marine depositional environment and anoxide. The results showed that the release of these occluded hydrocarbon, which are remnants from the original oil, can be a tool for the geochemical study of highly biodegraded oils, leading to better maturation and origin information.
