Knowledge of the in situ stress field of the Australian continent has increased greatly since compilation of the World Stress Map in 1992, principally by analysis of borehole breakouts and drilling-induced tensile fractures in petroleum wells. Stress orientations are variable across the Australian continent as a whole. However, within 15 of 16 individual stress provinces defined in the Australian continent (of one to a few hundred kilometres scale), mean stress orientations are statistically…

Influences of plate-boundary forces on the regional intraplate stress field of continental Australia
The Indo-Australian Plate is unique compared to other plates in that the maximum horizontal stress (σ H m a x ) orientation is not uniform and does not parallel the direction of absolute plate
The present-day stress field of Australia: New release of the Australian Stress Map
The present-day stress field is important for a range of earth science disciplines including petroleum and geothermal geomechanics, mine safety, neotectonics and seismic hazard assessment. So far,
The present-day stress field of New South Wales, Australia
ABSTRACT The Australian continent displays the most complex pattern of present-day tectonic stress observed in any major continental area. Although plate boundary forces provide a well-established
Three-dimensional finite-element modelling of the tectonic stress field in continental Australia
Traditionally, intraplate stress orientations have been modelled using an isotropic elastic plate. For the Australian Plate this method has been applied successfully to model the first-order pattern
The Tectonic Stress Field in Eastern Australia
Flexural analysis of geological structures in eastern Australia, based on gravity and topographic data, su13gests that the flexural rigidity of the fold belts is about 3.6 - 4.4 x 10-- Nm. This
Maximum horizontal stress orientations in the Cooper Basin, Australia: implications for plate-scale tectonics and local stress sources
SUMMARY Borehole breakouts and drilling-induced tensile fractures (DITFs) were interpreted in 61 wells in the Cooper Basin indicating an average maximum horizontal stress orientation of 101 ◦ N. A
The role of faults and fractures in local and regional perturbation of present-day horizontal stresses - An example from the Clarence-Moreton Basin, Eastern Australia
The present-day stress field has numerous applications in both conventional and unconventional hydrocarbon reservoirs, particularly for borehole stability, reservoir drainage and flooding patterns,
In situ stress distribution and mechanical stratigraphy in the Bowen and Surat basins, Queensland, Australia
Abstract We present regional in situ stress analyses based on publicly available log and pressure data from coal seam gas developments in the Permian Bowen basin, Australia. Together with earlier
Plate boundary forces are not enough: Second‐ and third‐order stress patterns highlighted in the World Stress Map database
The World Stress Map Project compiles a global database of contemporary tectonic stress information of the Earth's crust. Early releases of the World Stress Map Project demonstrated the existence of
New constraints on the neotectonic stress pattern of the Flinders and Mount Lofty Ranges, South Australia
The majority of published in-situ stress information in the Australian continent is confined to petroleum provinces where industry technologies facilitate the capture of contemporary crustal stress


Topography, boundary forces, and the Indo‐Australian intraplate stress field
The relative contribution of topographic (e.g., ridge push, continental margins, and elevated continental crust) and plate boundary (e.g., subduction and collisional) forces to the intraplate stress
The crustal stress pattern in the Australian continent
The state of stress in the crust is an important factor in the design and performance of underground excavations, the behaviour of oil reservoirs and in the design and construction of major civil
First‐ and second‐order patterns of stress in the lithosphere: The World Stress Map Project
To date, more than 7300 in situ stress orientations have been compiled as part of the World Stress Map project. Of these, over 4400 are considered reliable tectonic stress indicators, recording
In situ stress field of eastern Australia
New in situ data based on hydraulic fracturing and overcoring have been compiled for eastern Australia, increasing from 23 to 110 the number of in situ stress analyses available for the area between
Statistical trends in the intraplate stress field
The World Stress Map (WSM) database contains thousands of intraplate stress indicators, with the potential to provide important constraint for arguments about the relationship between tectonic
Global patterns of tectonic stress
Regional patterns of present-day tectonic stress can be used to evaluate the forces acting on the lithosphere and to investigate intraplate seismicity. Most intraplate regions are characterized by a

The theory and mechanics of a statistical smoothing algorithm for estimating stress fields based on observed data are described. Incorporated into the algorithm are tunable parameters which allow the
