Integrated dynamic models of subduction initiation, slab evolution, arc - back-arc deformation and mantle convection. A major debate in plate tectonics concerns the driving mechanism for formation of extensional back-arc basins in the overriding plate along a convergent tectonic boundary, where a subducting plate is thrust into the mantle underneath an overriding plate. One hypothesis states that such extension results from sinking and rollback of the subducting plate. The physical validity of t ....Integrated dynamic models of subduction initiation, slab evolution, arc - back-arc deformation and mantle convection. A major debate in plate tectonics concerns the driving mechanism for formation of extensional back-arc basins in the overriding plate along a convergent tectonic boundary, where a subducting plate is thrust into the mantle underneath an overriding plate. One hypothesis states that such extension results from sinking and rollback of the subducting plate. The physical validity of this hypothesis will be tested using both laboratory and numerical modelling techniques. The modelling will investigate overriding plate - subducting plate - mantle interaction in three-dimensional space and quantify the role of key physical parameters on the subduction process.Read moreRead less
Exploring deep Australia: 3-D imaging of the lithosphere beneath south-east Australia using multiple high density seismic arrays. The successful completion of this project will significantly improve our knowledge of the seismic structure of the Australian lithosphere, and hence improve our understanding of how the Australian continent came to be formed.

The successful completion of this project will significantly improve our knowledge of the seismic structure of the Australian lithosphere, and hence improve our understanding of how the Australian continent came to be formed. In addition, the tomographic imaging methods that will be developed and applied to the individual and combined seismic arrays have a direct relevance to the seismic imaging techniques used by the exploration industry. Finally, the creation of a combined dataset comprising records from ~300 stations will help keep Australia at the leading edge of observational seismology, as other countries (e.g. U.S.) begin to deploy very large seismic arrays.Read moreRead less
Large-scale three dimensional deformation of the lithosphere by subduction and mantle flow. We will be modelling of the dynamics of the Earth's crust and shallow lithosphere in response to the huge stresses created by plate motions. For Australia these stresses are transmitted from the distant plate boundaries, but they have a direct controlling influence on the evolution of the petroleum rich basins of Australia. These basins have reached maturity; further exploration will be in deep water wher ....Large-scale three dimensional deformation of the lithosphere by subduction and mantle flow. We will be modelling of the dynamics of the Earth's crust and shallow lithosphere in response to the huge stresses created by plate motions. For Australia these stresses are transmitted from the distant plate boundaries, but they have a direct controlling influence on the evolution of the petroleum rich basins of Australia. These basins have reached maturity; further exploration will be in deep water where geophysical prospecting methods are unreliable. Model-driven "exploration geodynamics" methods such as those we are developing will be needed to support traditional exploration techniques in these areas.Read moreRead less
Southern gateways - the icehouse cometh: Eocene to Oligocene evolution of southeast Australia. The 50 to 30 million years old strata of southeastern Australia have great economic importance for Australia. Most of the gas and oil extracted in the region comes from strata of this age. The research will lead to better age constraints on these reserves, thus enhancing petroleum prospectivity in the area. The global environment changes from 50 to 30 million years charted in this project will lead ....Southern gateways - the icehouse cometh: Eocene to Oligocene evolution of southeast Australia.

The research will lead to better age constraints on these reserves, thus enhancing petroleum prospectivity in the area. The global environment changes from 50 to 30 million years charted in this project will lead to a better understanding of the geological record of greenhouse-icehouse change. Knowledge of the nature of this change in the past is critical to predicting how our climate is going to behave in the future.Read moreRead less
Pore scale characterisation of the wettability of petroleum reservoir core material: Towards optimised recovery of hydrocarbon reserves. In most oil reservoirs more than 50% of original oil in place remains unrecovered. A major factor contributing to suboptimal recovery is insufficient knowledge of the rock wettability. Even a small improvement in recovery will have substantial economic benefit. The proposed project aims to characterise wettability in hydrocarbon bearing rocks using advanced 3D ....Pore scale characterisation of the wettability of petroleum reservoir core material: Towards optimised recovery of hydrocarbon reserves. In most oil reservoirs more than 50% of original oil in place remains unrecovered. A major factor contributing to suboptimal recovery is insufficient knowledge of the rock wettability. Even a small improvement in recovery will have substantial economic benefit. The proposed project aims to characterise wettability in hydrocarbon bearing rocks using advanced 3D imaging hardware and understand implications to oil displacement and recovery via state-of-the-art computational tools. Scientifically, this will be a leading edge research achievement enhancing Australian competitiveness in petroleum engineering research and will help Australia become a world leader in the export-oriented petroleum research services industry.Read moreRead less

Double and triple dating are exciting new ANU-Yale breakthroughs that can be used to more accurately identify the source of sediment in rivers and sedimentary rocks than is possible using existing techniques. They have fundamental applications in the study of erosion, tracing the source of heavy minerals in titanium deposits and in determining the source of sedimentary sequences that host oil. Under favourable circumstances double dating can be used also to date sediments that are devoid of fossils, which has direct application in oil exploration.Read moreRead less

Petroleum exploration in deepwater areas offshore Australia is becoming increasingly important as more accessible, shallow water oil reserves near exhaustion. Geological simulation is an important tool for understanding deep water basins where geophysical imaging techniques are less effective. This project will develop 3D computational models relevant to understanding the development and evolution of geological basins and the sediments that fill them. The models will be integrated with available offshore data for potentially prospective Australian basins in the Northwest Shelf and the Southern Australian margin.Read moreRead less
