The Kolo Creek E2.0 reservoir oils from the Nigerian Niger Delta region have been studied for molecular marker by characterisation using full scan GC-MS and GC-MS-MS transition from 412 → 369.
An existing molecular marker compound normally found in coals and lignites has been observed in some these oils. This molecular marker – Lupane, sustains the biogenic origin of these oils as terrigenous and it is very similar to Oleanane.
