- •
Mixed oils from distinct sources, maturity levels and ages were identified.
- •
δ13C of long chain n-alkanes differentiates Triassic from Jurassic contributions.
- •
δ13C of n-alkanes was suitable for quantifying oil source contributions.
- •
Diamondoids suggest a late gas charge in the entire Hammerfest Basin.
- •
Secondary oil migration seems not to have significant effects on δD of n-alkanes.
