“…Fluorene was found together with four methyl fluorene (MF) and eight dimethyl fluorene (DMF) biomarkers. MF distribution showed the presence of 3-MF, 2-MF, 1-MF, and 4-MF as seen in the chromatogram in Figure 5 [18,58] where 1-MF showed the highest amount compared to other isomers. It is suggested that 1-MF was obtained from the cyclization reaction of 2,3-dimethyl biphenyl (2,3-DMBP) and its presence will be more abundant as increasing sample maturity [38].…”

“…As the presence of these isomers was not identified in the oil sample, the presence of benzo(b)naphto(2,1-d)thiophene was unable to provide the expected information. However, the presence of triterpenoid de-A-aromatic biomarker identified in Cepu oil indicates organic input derived from higher plant especially Angiosperms [58].…”

“…Fluorene, DBT, and DBF may originate from biphenyl precursor, but were formed in different environment [56,57]. Fluorene is a typical indicator of the organic sources deposition in deltaic, estuary or river estuaries, fresh water lacustrine, and brackish lacustrine [39,58], whereas dibenzothiophene (DBT) in oil is originating from marine and saline lacustrine environment [18]. Oil derived from the paludal facies and coal deposit environment is characterized by the dominance of DBF [59].…”

“…This is due to mosses as the only organism that produces dibenzofuran compounds through secondary metabolism, likewise, the presence of dibenzothiophene as an indicator of the level of thermal maturity through the substitution of methyl groups such as methyl dibenzothiophene (MDBT) and dimethyl dibenzothiophene (DMDBT) [37]. [58].…”

“…In DMF group, only 1,7-DMF isomers were identified [57]. The presence of fluorene and their homologues indicate the aquatic environment, such as delta, estuary, fresh water lacustrine, and brackish lacustrine depositional environment [58,60]. The dibenzofuran compound (DBF) is found together with methyl dibenzofuran (MDBF) and dimethyl dibenzofuran (DMDBF).…”

Biomarkers identification of aromatic hydrocarbon fraction of Cepu oil samples was carried out to determine the ancient depositional environment, the source of origin and indicators of the maturity of the old well of the Cepu Block oil, Wonocolo Formation, East Java Indonesia. Biomarkers was identified through the Gas Chromatography-Mass Spectroscopy (GC-MS) method. The distribution of aromatic hydrocarbon biomarkers indicates the presence of naphthalene compounds and their derivatives, sesquiterpenoids, diterpenoids and heterocyclic aromatic groups. The presence of identified biomarkers indicates the source of the oil organic compound coming from higher plants Angiosperms. The presence of methyl phenanthrene and aromatic heterocyclic biomarkers such as dibenzothiophene and dibenzofuran , as well as fluorene shows that Cepu Block oil was deposited not only in the terrestrial environment, but also lacustrine and marin under oxidic precipitation conditions. The presence of methyl phenanthrene with MPI value of 0.86 and isocadalene abundance higher than cadalene indicates moderate to high maturity of the Cepu Block oil analyzed. Keywords: Cepu Block oil, aromatic hydrocarbon, biomarker, paleoenvironment, GC-MS analysis.

In this study, we combined the geochemical characteristics based on Rock-Eval pyrolysis and gas chromatography – mass spectrometry (GC–MS) results with the facies analysis. These surveys were conducted within grey to black claystones/mudstones intervals of the Podil’tsi and Kokhanivka formations, related to the Pliensbachian and Toarcian–Bathonian ages, respectively. The geochemical results revealed that the Podil’tsi Formation contains mixed marine/terrigenous, early-mature to mature organic matter. The deposition of this formation took place in dysoxic redox conditions of a sulphate-poor marine palaeoenvironment, with oxygen scarcity within the photic zone, as documented by green- and brown-pigmented Chlorobiaceae. Oleanane is present within the samples from the Podil’tsi Formation, which is uncommon within Lower Jurassic sedimentary rocks. The Kokhanivka Formation contains mostly early-mature, terrestrial organic matter, deposited in suboxic conditions of a sulphate-poor, fluvial–deltaic palaeoenvironment. The absence of aliphatic diterpenoids within the Middle Jurassic strata points to the low significance of conifers in the sediment supply area at this time. All of the Podil’tsi and most of the Kokhanivka formations are characterised by poor hydrocarbon potential. Only the middle part of the Kokhanivka Formation, built by brown, organic-rich claystones, shows fair-to-good hydrocarbon potential. Based on our results, a chemostratigraphic correlation of the Toarcian–Bathonian strata from the Carpathian Foredeep with the same strata from the neighbouring Polish Basin was performed. The juxtaposition of the geochemical and facies results suggests that the interval of brown organic-rich claystones, from the middle part of the Kokhanivka Formation can be related to the Middle–Upper Aalenian Age.
