“…In-depth studies of the compound library indicate that hydrocarbons with higher aromaticity are preferentially retained in hydrocarbon source rocks during primary transport, especially for high DBE compounds with low carbon numbers. These findings confirm that the functional groups, aromaticity, and degree of alkylation of hydrocarbons and non-hydrocarbons are the main factors influencing the fractionation of petroleum components during primary transport (Figure 8) [92]. Wax deposition is a great concern in the petroleum industry because it can cause a partial or total blockage of pipelines.…”

The progress in ultrahigh-resolution mass spectrometry (UHRMS) and related technologies has significantly promoted the development of petroleomics. The study of petroleomics has greatly broadened our knowledge of the composition of petroleum at the molecular level, especially heavy fractions that cannot be analyzed by gas chromatography (GC)-based methods. To date, heteroatom-containing (O, N, S, and metal atoms) compounds in petroleum have been studied extensively by UHRMS. Nevertheless, the main components of petroleum, hydrocarbon compounds, have remained out of reach of petroleomics characterization for a long time because they are too difficult to be softly and efficiently ionized for UHRMS analysis. It is undoubtedly the case that petroleum hydrocarbons should not be the missing part of petroleomics characterization since they play important roles not only as feeding pools for various high value-added petroleum products but also as critical biomarkers for geochemistry studies. Here, the most recent breakthroughs in petroleomics characterization of hydrocarbon compounds using UHRMS rather than conventional methods have been reviewed. Innovations of soft ionization methods can transform non-polar hydrocarbon molecules into molecular ions or quasi-molecular ions that are reachable for UHRMS without fragmentation. The development of data processing methods has assisted the decoding of the complicated UHRMS data to visualize the molecular composition and structure of hydrocarbon compounds. These advances make it possible to see the whole picture of petroleum compositions, from light distillation fractions to heavy distillation fractions, and from small volatile molecules to large non-volatile ones. The applications of UHRMS-based methods for petroleomics characterization of hydrocarbon compounds in crude oils and various petroleum samples including fuel oil, slurry, and even asphaltene have made a great contribution to petrochemistry and geochemistry studies, especially in the fields of molecular refining and biomarker discovery.

“…The TMIA of the samples exceeds 50%, except for the samples obtained at a depth of 3866 m (Tmax = 579 °C). The HC compounds can be divided into three groups: DBE1-5, DBE6-15, and DBE15 +, corresponding to low, medium, and high DBE groups representing compounds with an increasing molecular size of the aromatic core structure (Han et al, 2022b). As the maturity increases, there is likely a strong decrease in signals, the consumption of HC in the polar molecular compounds of the shale organic matter decreases sharply due to pyrobitumen formation (Mahlstedt et al, 2022), and the TMIA is 0.97%-6.79%.…”

“…The polar compounds preferentially adsorb onto charged mineral surfaces. Thus, when captured in minerals, inclusion oils generally contain a higher proportion of polar compounds and, therefore, show a red shift relative to the associated reservoir oils (e.g., Han et al, 2022;Nedkvitne et al, 1993;Stasiuk and Snowdon, 1997). Considering the paragenetic sequence and the UV fluorescence of hydrocarbon-bearing FIAs, the equant calcite presumably trapped heavier oils, containing more polar compounds than the postdating counterparts (quartz and fracture-filling calcite).…”
