Geochemical characterization of lacustrine and marine oils from off-shore Brazilian sedimentary basins using negative-ion electrospray Fourier transform ion cyclotron resonance mass spectrometry (ESI FTICR-MS)
Organic Geochemistry(2018)
摘要
•Petroleomic was applied to 69 off-shore Brazilian crude oils samples.•Kerogen type plays an important control on NSO compounds.•Clear separation based on polar species found in marine and lacustrine oils.•Negative ESI FTICR-MS can be used to perform geochemical assessment in crude oils.
