Biomarker evidence for Botryococcus and a methane cycle in the Eocene Huadian oil shale, NE China
TL;DR: The saturated and unsaturated hydrocarbons of two samples (HD-19 and HD-21) from the same section of the Middle Eocene lacustrine Huadian oil shale in NE China were identified and shown to be mainly from algal and bacterial sources.

Acyclic isoprenoid biomarkers and evolution of biosynthetic pathways in green microalgae of the genus Botryococcus
John K. Volkman,John K. Volkman +1 more
TL;DR: It seems likely that the Botryococcus species recorded in sediments predating the Eocene lacked the ability to produce botryococcenes or lycopadiene, but nonetheless still contained polymeric non-isoprenoid alkyl chains in the form of an algaenan which on preservation gave rise to a multitude of organic rich rocks.

Oil families and their inferred source rocks in the Barents Sea and northern Timan-Pechora Basin, Russia
TL;DR: In this article, a geochemical study of 34 oil samples was conducted to understand the types and distributions of effective source rocks and evaluate the geographic extent of the petroleum systems in the Barents Sea and northern Timan-Pechora Basin.
Journal ArticleDOI
Khatatba Formation as an active source rock for hydrocarbons in the northeast Abu Gharadig Basin, north Western Desert, Egypt
TL;DR: In this paper, a suite of oil samples collected from wells drilled in the northeastern part of the Abu Gharadig Basin were studied to determine the petroleum potential of the Middle to Late Jurassic Khatatba Formation as a source rock for oil produced in the basin.
Journal ArticleDOI
Screening of oil sources by using comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry and multivariate statistical analysis.
TL;DR: Using comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry, volatile and semi-volatile organic compounds in crude oil samples from different reservoirs or regions were analyzed for the development of a molecular fingerprint database.

TL;DR: The second edition of The Biomarker Guide as mentioned in this paper provides a comprehensive account of the role that biomarker technology plays both in petroleum exploration and in understanding Earth history and processes.
Journal ArticleDOI
A review of sterol markers for marine and terrigenous organic matter
TL;DR: It is indicated that inferences drawn from sterol distributions regarding sources of organic matter must be made with caution and should be supported using other lipid data, and that in ancient sediments and crude oils a high proportion of C 29 steranes need not indicate that most of the organic matter was derived from vascular plants.
Journal ArticleDOI
A new method for the deoxygenation of secondary alcohols
TL;DR: In this paper, a general synthesis of O-cycloalkyl thioesters has been developed which gives access to O-cycle-alkyl seleno-formates and selenobenzoates.
Journal ArticleDOI
Relationship Between Petroleum Composition and Depositional Environment of Petroleum Source Rocks
TL;DR: In this paper, a novel parameter based on the presence of C30 steranes in the oil was found to be a definitive indication of a contribution to the source from marine-derived organic matter, which can be used to gauge relative amounts of higher plant input to oils within a given basin.
