Many of the earliest laboratory studies of the brittle-ductile transition were on porous rocks,
with a focus on the evolution of failure mode from brittle faulting to cataclastic flow with …

Bentheimer sandstone outcrop samples are ideal for laboratory studies due to their lateral
continuity and block scale homogeneous nature. Over the years they have been used to …

Understanding the mechanical behaviour of reservoir rock under different temperatures with
different cooling conditions is necessary for safe and effective deep geo-engineering …

Rock failure is a serious problem in rock engineering environments. Rock failure modes,
however, are complex and difficult to quantify or predict. A comprehensive study on rock …

Geothermal heat has now been identified as an effective renewable energy source due to
severe environmental impacts created by conventional fossil usage on global climatic …

The coupled development of compaction and strain localization may significantly impact the
stress field, strain partitioning and fluid transport. To investigate the phenomenon of …

We conducted an extensive suite of true triaxial experiments in two porous sandstones,
Bentheim (porosity≈ 24%) and Coconino (17.5%). Our experiments demonstrate that failure …

Conventional triaxial compression and “reducing confining pressure” experiments were
carried out for red sandstone by an MTS815 Flex Test GT rock mechanics experimental …

Thermal stimulation method can be effectively utilized to enhance the flow performance in
the tight porous media with an induced thermal shock. This approach can be applied to …

In view of a previous study of the intermediate principal stress effect at a limited σ 2 range, a
series of true triaxial tests, covering a full range of intermediate principal stresses that vary …
