Maximum horizontal stress orientations in the Cooper Basin, Australia: implications for plate-scale tectonics and local stress sources

Abstract: 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 total of 890 borehole breakouts and 608 DITFs were interpreted in the Cooper Basin. The approximately east–west maximum horizontal stress orientation is consistent over much of the basin, except in the Patchawarra Trough where maximum horizontal stress rotates to a northwest–southeast orientation. This rotation in maxi… Show more

“…The orientation of the maximum horizontal stress in the Cooper Basin can be determined using breakouts and drilling-induced tensile fractures (DITFs) observed on image logs and/or caliper logs [15]. The orientation of S Hmax is predominantly east-west (0901N) throughout the Cooper Basin although there appears to be some local stress rotation adjacent to faults (Fig.…”

“…Several studies have been undertaken to determine the in situ stress tensor in the Cooper Basin [13][14][15]. Here we summarise previous relevant studies to constrain the magnitudes of the minimum horizontal stress, vertical stress and the orientation and magnitude of the maximum horizontal stress in the Cooper Basin.…”

“…Cooper Basin in situ stress is strike-slip at shallow depth and transitions into reverse fault regime at depth (about 3km) while the principal maximum horizontal stress (S H ) direction is consistent at approximately N100°E (King, et al 2011, Reynolds, et al 2005). In our study area, the target Permian tight gas sand is at a depth of about 2.2 -2.4km depth.…”

“…The Cooper and Eromanga sedimentary basins (~3.6 km thick) act as an insulating cap over the granitic EGS reservoir (Holl and Barton 2015). The project area is characterized by a compressive stress field oriented approximately in E-W direction (Reynolds, et al 2006, Reynolds, et al 2005. In November 2012, the Habanero-4 well was stimulated by injecting 36.5 ML of near-surface aquifer-sourced water (13 Ωm at 25°C) over 14 days (Hogarth, et al 2013, Holl and Barton 2015, McMahon and Baisch 2013.…”
