Present-Day Crustal Stress Field of North-Eastern Australia. The key project benefit is to advance fundamental understanding of crustal dynamics in NE Australia and thus Australia as a whole. The project will improve our knowledge of both the nature and sources of the present-day crustal stresses in NE Australia. The project has implications for seismicity and neotectonics in NE Australia. Furthermore, the project has significant implications for both hydrocarbon and hot dry rock geothermal ener ....Present-Day Crustal Stress Field of North-Eastern Australia.

A new geomechnical tool for the evaluation of hydrocarbon trap integrity. Hydrocarbon exploration drilling is an intrinsically high risk, high cost activity. Even once a potential reservoir is located there remains the possibility that under recent geological activity the trap has become breached and leaked due to failure of overlying or adjacent rock. This Project will develop a technique that builds on current predictive techniques, and numerical modelling methods, to produce a series of sub-s ....A new geomechnical tool for the evaluation of hydrocarbon trap integrity. Hydrocarbon exploration drilling is an intrinsically high risk, high cost activity. Even once a potential reservoir is located there remains the possibility that under recent geological activity the trap has become breached and leaked due to failure of overlying or adjacent rock. This Project will develop a technique that builds on current predictive techniques, and numerical modelling methods, to produce a series of sub-surface geomechanical models for four important petroleum basins. This new and integrated geomechanical approach will improve current predictive capabilities for detecting breached traps, thus enhancing prospectivity in the major petroleum provinces of Australia.Read moreRead less
The Australasian Stress Map. The contemporary crustal stress field of Australasia is both more complex and more poorly constrained than that of other continental areas. The crustal stress field controls processes including earthquake hazard; the stability of mines, tunnels and boreholes, and; fluid flow in groundwater aquifers and oil reservoirs. Using data from oil exploration wells, earthquakes and recent geological activity, this project will increase from around 300 to 1000 the number of rel ....The Australasian Stress Map. The contemporary crustal stress field of Australasia is both more complex and more poorly constrained than that of other continental areas. The crustal stress field controls processes including earthquake hazard; the stability of mines, tunnels and boreholes, and; fluid flow in groundwater aquifers and oil reservoirs. Using data from oil exploration wells, earthquakes and recent geological activity, this project will increase from around 300 to 1000 the number of reliable stress determinations available for Australia, New Zealand and Papua New Guinea. The stress field will be modelled in order to improve our understanding of its origin and variability.Read moreRead less
