New molecular and isotopic biomarker approaches to establishing source, palaeoclimate, facies and thermal history of sedimentary organic matter. The ability to identify crude oil sources is a key issue in petroleum exploration, especially in Australia where vast gas deposits occur but very limited reserves of liquid hydrocarbons have been discovered.

The ability to identify crude oil sources is a key issue in petroleum exploration, especially in Australia where vast gas deposits occur but very limited reserves of liquid hydrocarbons have been discovered. Discoveries of new petroleum reservoirs/provinces will benefit all Australians. Technological developments made will be extended to other Australian basins leading to more effective petroleum and mineral exploration strategies. The project described will also help our understanding of climate variability of past episodes and help predict what might happen in the future. The PhD scholars will foster high-calibre postgraduate research students suitable for employment in research or in industry.Read moreRead less

Summary
Accelerated solvent extractor and evaporator for molecular and stable isotope analyses of sedimentary organic matter. The accelerated solvent extractor (ASE) uses pressurised liquid extraction to obtain the bitumen fraction easily measurable for molecular and isotopic composition of organic sediments in just a few minutes. This compares favourably to traditional extraction procedures, which can take two to three days. Our projects often require the analyses of large numbers of sediment extracts ....Accelerated solvent extractor and evaporator for molecular and stable isotope analyses of sedimentary organic matter. The accelerated solvent extractor (ASE) uses pressurised liquid extraction to obtain the bitumen fraction easily measurable for molecular and isotopic composition of organic sediments in just a few minutes. This compares favourably to traditional extraction procedures, which can take two to three days. Our projects often require the analyses of large numbers of sediment extracts to obtain chemical data at high geological resolution. The ASE/Evaporator will greatly assist these endeavours which aim to improve our understanding of Australian environments (incorporating the effects of natural and human-related processes) and identify source rocks offering good petroleum reserves.Read moreRead less

This facility will improve our ability to forecast environmental responses to future climate change, and help Australia manage current threats to its biodiversity. Furthermore, this research will increase the ability to identify crude oil sources, to the benefit of petroleum exploration in Australia. This facility will also contribute to an improved understanding of controls on water quality and will help to protect our precious freshwater resources, already under intense pressure from climate change. Importantly, this project will enable students and young professionals to be trained in state-of-the-art technology, leading to quality scientists ready for employment in industry.

Reduction of risk in exploration for petroleum liquids. Australia has an urgent need to establish additional reserves of crude oil. A feature of petroleum exploration in recent decades has been discovery of vast reserves of natural gas but an inability to replace our diminishing reserves of crude oil. Clearly new technology is required to enhance our capability to recognise crude oil-prone rather than gas-prone source rocks. The proposed project will establish the fundamental geochemical pro ....Reduction of risk in exploration for petroleum liquids.

Clearly new technology is required to enhance our capability to recognise crude oil-prone rather than gas-prone source rocks. The proposed project will establish the fundamental geochemical processes that will support the potential exploration techniques, developed with Woodside Energy Limited support.Read moreRead less
A terrestrial hot spring setting for the origin of life. This project aims to test the proposal that a terrestrial hot spring field could have been the setting for the origin of life, in preference over the currently favoured site at deep sea vents. The project will involve an integrated, and multi-disciplinary study of the rocks, fluids, and molecules that together make up ancient to modern hot spring systems, and experiments on prebiotic organic chemistry using early Earth materials.

Maintaining the quality of water and soil is a critically important issue for Australia's economic and social development. To be able to predict and plan the future of our natural assets, it is critical to understand their ecological past and their state before and after European settlement. We will utilize the new instrument to develop and apply innovative technologies providing Australia with new knowledge about the causes and effects of toxic cyanobacterial blooms, eutrophication, and contamination of reservoirs by bush-fires. The new facility will also supply advanced oil fingerprinting techniques to the petroleum industry minimizing exploration risk and increasing the chance of the discovery of new oil deposits.Read moreRead less
