Abstract
A review on the utilization of petroleum hydrocarbons of
is~prenoid, hopanoid and steranoid nature in organic geochemical
studies is given together with the role of trace metals in the science
of petroleum.
A number of crude oils from Egyptian oil fields in the Gulf of
Suez and the Western Desert were selected for the present
investigation. They were analyzed for their hydrocarbon and trace
metal contents by column and gas chromatography, mass
spectrometry and atomic absorption spectroscopy.
The geochemical studies involved oil-oil, oil-source rock and
oil-maturity correlations. These included both bulk and biomarker
parameters to relate and classify the oils into genetic groups.
The bulk correlation characterized the Gulf of Suez oil,
Zaffarana, with anoxic marine depositional environment and the
Shushan basin oils, Khalda, Salam, and UmBaraka, with nonmarine
paleoenvironment. However, the depositional environments of the
remaining oils from Dahab Merrier basin, Alamein and Hourus, as
well as AbuEIGharadig basin oil, WD-33, and AbuSenan basin oil,
TSW-16, were not completely characterized by bulk correlations
alone.
The n-alkane distribution patterns of oils showed an aliphatic
hydrocarbon dominance and excluded any biodegradation. They also
characterized the source organic input of the oils, Zaffarana, WD-33,
and TSW-16 as of marine matter derived from algae and/or bacteria.
However, the gas chromatogram traces of Khalda, Hourus.
