Abstract(unpublished)
The Paktoa C-60 oil from Beaufort Mackenzie Basin has experienced severe biodegradation. It's moderate API gravity, low asphaltene content and high content of diamondoids seem to indicate that the oil was mainly originated from a source rock at late oil to early gas generation stage, probably of Cretaceous age. Source contribution from the Tertiary sequence is likely of secondary importance, and is more likely due to the migration pickup.
Summary(Plain Language Summary, not published)
The Paktoa C-60 oil from Beaufort Mackenzie Basin has experienced severe biodegradation. It's moderate API gravity, low content of asphaltene and high content of diamondoids seem to indicate that the oil was mainly sourced from a thermally highly mature source rock of Cretaceous age. Source contribution from the Tertiary sequence is likely of secondary importance, and is more likely due to the migration pickup.
