The identification of key acid metabolites ('signature' metabolites) has allowed significant improvements to be made in our understanding of the biodegradation of petroleum hydrocarbons, in reservoir and in contaminated natural systems, such as aquif

Because of the great variety of lacustrine-source depositional characteristics and biological consortia, identification of a universally applicable indicator of freshwater or brackish-water organic input for crude oils and rock extracts has proven el

Two C26 sterane ratios, the 24-nordiacholestane ratio (NDR) and the 24-norcholestane ratio (NCR), are useful for assessing petroleum source age. Values for these parameters generally increase in the Cretaceous when diatoms were rapidly radiating and

The large volumes of 'supercomplex' mixtures of reputedly toxic organic compounds in acidic extracts of oil sands process-affected waters (OSPW) represent a challenging goal for complete characterisation. To date, comprehensive two-dimensional gas ch

The timing and extent of hydrocarbon generation depends on both the thermal/burial history of a source rock interval and the reaction kinetics of hydrocarbon generation from the associated kerogen. The present study is focused on understanding reacti

Biomarkers, molecular fossils, are organic compounds in Holocene to Precambrian sedimentary deposits that can be related to specific chemical compounds produced in the biosphere. We demonstrate here that 24-norcholestane biomarkers, i.e., C26 sterane
