Geochemistry and origin of Ordovician oils in the Rewapu Block of the Halahatang Oilfield (NW China)

Abstract: The oils in the Rewapu Block of the Halahatang Oilfield in the Tarim Basin (northwestern China) were geochemically analyzed by gas chromatography-mass spectrometry to investigate their origin and possible secondary alteration. The physical properties and chemical compositions of these Ordovician oils vary greatly, ranging from light to extremely heavy oils. All these oils belong to one single population and were derived from same source kitchen/bed. The differences in their chemical compositions and physical p… Show more

“…All rocks have been Soxhlet extracted and the extractable organic matter (EOM) has been separated into saturate, aromatic, resin and asphaltene fractions. Gas chromatographymass spectrometry has been performed on saturate and aromatic hydrocarbon fractions following the standard procedure (Chang et al, 2018;Fang et al, 2015;Tang et al, 2019). All compounds were identified by comparison of relative retention time and mass spectrum with those of literature.…”
