A mutlidisciplinery approach using molecular organic geochemical analyses combined with geological information will innovatively contribute to a coherent portrayal of the decline, collapse and subsequent recovery of biological species at the Permian/Triassic extinction event in Western Australia and other parts of the world. The proposed study will particulary focus on environmental changes closely related to deposition of petroleum source rocks globally but also focussing on the Perth Basin of the Triassic. This information will then be used to better identify rocks in Australia offering good sources of petroleum.Read moreRead less

Summary
Extension to Stable Isotope Facility: Elemental Analyser and GC-GC Preparative Systems. To carry out compound specific stable isotope analysis, compounds need to be resolved by GC, and with samples such as petroleum, this is uncommon. We therefore seek to explore GC-GC as a novel additional preparative system in isotope ratio mass spectrometry. Within our new State Centre of Excellence we will be confronted with samples such as soils, sediments, and natural organic matter which require examinati ....Extension to Stable Isotope Facility: Elemental Analyser and GC-GC Preparative Systems. To carry out compound specific stable isotope analysis, compounds need to be resolved by GC, and with samples such as petroleum, this is uncommon. We therefore seek to explore GC-GC as a novel additional preparative system in isotope ratio mass spectrometry. Within our new State Centre of Excellence we will be confronted with samples such as soils, sediments, and natural organic matter which require examination by bulk isotope analysis. If equipped with a customised elemental analyser as an inlet system, both our existing mass analysers will be capable of measuring carbon, hydrogen, nitrogen, oxygen and sulphur isotope values of whole samples.Read moreRead less
Stable Carbon and Hydrogen Isotope Signatures of Chemical Fossils to Infer Palaeoenvironmental Change. Aims are to selectively measure the stable carbon and hydrogen isotopic composition of individual chemical fossils (biomarkers) in sediments and petroleum. Biomarkers are derived from biochemicals in algae, bacteria and higher plants and their isotopic compositions reflects important information about the climate and environment under which the precursor organisms lived. Periods of palaeoenvir ....Stable Carbon and Hydrogen Isotope Signatures of Chemical Fossils to Infer Palaeoenvironmental Change. Aims are to selectively measure the stable carbon and hydrogen isotopic composition of individual chemical fossils (biomarkers) in sediments and petroleum. Biomarkers are derived from biochemicals in algae, bacteria and higher plants and their isotopic compositions reflects important information about the climate and environment under which the precursor organisms lived. Periods of palaeoenvironmental change will be established through the varied stable isotope compositions of certain biomarkers within samples sectioned from sediment profiles of different age. This information will then be used to better identify rocks in Australia offering good sources of petroleum.Read moreRead less
TRANSIENT VIBRATION IN PIPELINE SYSTEMS. Although the threat of transient vibration to the safety of pipeline systems has been widely recognised, neither the coupling characteristics in transient wave propagation are clearly understood, nor accurate tools are available for analysing them. The aims of this project are to develop effective analytical and experimental methods, to study the interactions between transient waves of different types at pipe joints and bends, and to experimentally charac ....TRANSIENT VIBRATION IN PIPELINE SYSTEMS. Although the threat of transient vibration to the safety of pipeline systems has been widely recognised, neither the coupling characteristics in transient wave propagation are clearly understood, nor accurate tools are available for analysing them. The aims of this project are to develop effective analytical and experimental methods, to study the interactions between transient waves of different types at pipe joints and bends, and to experimentally characterise the transient excitations. The understanding and techniques developed from this project hold promise in providing reliable tools for safe design of complex pipeline systems in petroleum, chemical and refinery industries.Read moreRead less
Scour and scour protection around gravity anchors. The costs for scour protection around gravity anchors in a typical offshore project are in the order of 10-20 million dollars. With the increasing number of gravity anchors being installed in Australian waters, significant cost savings are expected to be achieved through improved understanding of local scour and scour protection around gravity anchors. The outcomes of this project can be applied directly to the design of new large diameter pipel ....Scour and scour protection around gravity anchors.

With the increasing number of gravity anchors being installed in Australian waters, significant cost savings are expected to be achieved through improved understanding of local scour and scour protection around gravity anchors. The outcomes of this project can be applied directly to the design of new large diameter pipelines, will lead to reduction of scour protection costs and enhancement of safety of the pipeline to be stabilized, and increase the competitiveness of Australian oil and gas industry.Read moreRead less
Seismic response of partially saturated petroleum reservoir zones: towards quantitative recovery monitoring. In most Australian reservoirs less than 50% of the original oil in place is recovered. A major factor that contributes to low recovery rates is bypassed oil/gas. Even a small, 1% improvement in recovery is of substantial economic significance. The proposed project aims to develop quantitative models for reservoir monitoring of zones with bypassed hydrocarbons using time-lapse (4D) seismic ....Seismic response of partially saturated petroleum reservoir zones: towards quantitative recovery monitoring. In most Australian reservoirs less than 50% of the original oil in place is recovered. A major factor that contributes to low recovery rates is bypassed oil/gas. Even a small, 1% improvement in recovery is of substantial economic significance. The proposed project aims to develop quantitative models for reservoir monitoring of zones with bypassed hydrocarbons using time-lapse (4D) seismic measurements, and thus to improve the hydrocarbon recovery factors. Developing these models will be a cutting edge research achievement, which will make a significant contribution to the knowledge base of the discipline and advance the international reputation of Australian science.Read moreRead less

Investigation of potential spudcan punch through failure. The safe and economic use of mobile jack-up structures is critical to the prosperous development of Australia's significant offshore oil and gas industry. However, their use is hindered by potential 'punch-through' failure during installation, when their large conical footings can unexpectedly and uncontrollably push a locally strong zone of soil into underlying softer material. To improve their safety, this research will investigate a po ....Investigation of potential spudcan punch through failure. The safe and economic use of mobile jack-up structures is critical to the prosperous development of Australia's significant offshore oil and gas industry. However, their use is hindered by potential 'punch-through' failure during installation, when their large conical footings can unexpectedly and uncontrollably push a locally strong zone of soil into underlying softer material. To improve their safety, this research will investigate a potential new site-investigation procedure and develop an appropriate calculation method for predicting failures for sites where sand overlies clay. Results will be based on a series of innovative physical and numerical experiments, and assessed against field data and existing industry standards.Read moreRead less

Under certain conditions a typical sea can becomes bimodal comprising of wind-driven seas and long period swells interacting from two directions. Using a nonlinear model, the occurrence and characteristics of bimodal and bi-directional seastates are quantified.
Low frequency oscillations of a moored offshore structure have profound design influence on the mooring system. A nonlinear response model for a floating vessel in bimodal and bi-directional seastates, will be developed using nonlinear dynamics techniques. The numerical models for the environment and the floating platform will be validated by experiments at the Ocean Basin in Canada.
The project adopts a holistic approach by considering the environment and the moored platform as a complex natural system. With excellent opportunities for technology transfer, the project also benefits from substantial in-kind contributions of the overseas PIs.
