Geomechanical properties related to top seal leakage in the Carnarvon Basin, Northwest Shelf, Australia
TL;DR: The Muderong Shale is the regional top seal in the Carnarvon Basin on the Northwest Shelf of Australia as mentioned in this paper, and it is assumed that pre-existing faults and fractures may well be critically stressed in the present-day stress field.

Geomechanical, microstructural, and petrophysical evolution in experimentally reactivated cataclasites: Applications to fault seal prediction
TL;DR: In this paper, a triaxial test was conducted to determine the failure envelopes for well-lithified cataclastic fault rocks from the Otway Basin, Australia, where fault reactivation is a significant risk to trap integrity.

Influence of physical and diagenetic processes on fault geomechanics and reactivation
TL;DR: In this article, the authors studied the geomechanical and capillary properties of cataclastic and phyllosilicate framework fault rocks and found that clay content influences mechanical properties both pre- and post diagenesis.

TL;DR: In this article, the effects of physical and diagenetic processes on these parameters in the Otway Basin on the southern margin of Australia were investigated and the results have direct implications for understanding the micromechanics of deformation in impure sandstones, for physical property evolution during and postfaulting, and for geomechanical prediction of fault reactivation.

TL;DR: In this article, failure envelopes for microstructurally and petrophysically characterised fault rocks are presented and applied to assess the risk of fault reactivation and associated seal breach at the proposed high-level radioactive waste repository site at Yucca Mountain, Nevada.
