Need, innovation, & benefit
In 2014, the International Geothermal Expert Group‘s forward looking report recommended ‘rebooting’ Australia’s geothermal industry. The report highlights a need for greater understanding of structural permeability at depth, to identify potential resources and de-risking geothermal projects ahead of drilling.
This project is the first investigation of the structural permeability of the Australian continent, achieved by applying advanced geophysical, geomechanical, and petrological techniques in a cross-disciplinary approach. This integration of datasets provided the basis for identifying structural permeability pathways, as well as helping to develop new methods for the detection of fractures beneath the Earth’s surface, and predicting how fluids will move through them.
The project will assist project development in engineered geothermal systems, in both sedimentary basins and crystalline basement regions. Better understanding of natural fracture distributions, attributes, and permeability will also provide data and insight for carbon capture and storage, unconventional gas resources, and groundwater resources.
stress, structure, and seismic
The stress, structure and seismic research group (S3) at the University of Adelaide consists of geoscientists and engineers with expertise in petroleum geology, geomechanics, tectonics and neotectonics, and seismic interpretation.
The Stress, Structure and Seismic Group has research funding from the ARC, the petroleum and geothermal industries, ARENA, and state government. Major projects include the The Australian Structural Permeability Map, Detachments in evaporites and shales, The Australian Stress Map, Present-Day Stress and Tectonics of Delta-Deepwater Fold-Thrust Belts, SE Asian Stress Map and Geomechanics and Structure of CO2 Sequestration. The group also provides consulting and training on in-situ stress determination, wellbore stability, fracture stimulation and seal integrity, seismic interpretation, 2D and 3D structural modelling (using Move and Dynel).
