Petroleomics: The Next Grand Challenge for Chemical Analysis

TL;DR: The key features that have opened up this new field have been ultrahigh-resolution FT-ICR mass analysis, specifically, the capability to resolve species differing in elemental composition by C(3) vs SH(4) (i.e., 0.0034 Da), thereby extending to >900 Da the upper limit for unique assignment of elemental composition based on accurate mass measurement.

Resolution of 11 000 Compositionally Distinct Components in a Single Electrospray Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrum of Crude Oil
TL;DR: Electrospray selectively ionizes only the basic compounds in a sample of South American crude oil, and mass scale expansion and graphical representations reveal increased heteroatom diversity, aromatic rings, and alkyl substitution with increased mass.

TL;DR: The main theme of the workshop as discussed by the authors was to understand the impact of selective degradation/preservation of organic matter (OM) in marine sediments on the interpretation of the fossil record, including the influence of the molecular composition of OM in relation to the biological and physical depositional environment, including new methods for determining complex organic biomolecules.

Two- and Three-Dimensional van Krevelen Diagrams: A Graphical Analysis Complementary to the Kendrick Mass Plot for Sorting Elemental Compositions of Complex Organic Mixtures Based on Ultrahigh-Resolution Broadband Fourier Transform Ion Cyclotron Resonance Mass Measurements
TL;DR: The three-dimensional van Krevelen diagram can completely separate different classes in pyridine-extracted coal or petroleum samples and can also graphically distinguish fossil fuels according to their nature, maturation, and processing.
