Abstract Knowledge of the mechanical behavior of planetary rocks is indispensable for
space explorations. The scarcity of pristine samples and the irregular shapes of planetary …

We present a micromechanical characterization of shales from the Horn River Basin, NW
Canada. The shales have contrasting mineralogy and microstructures and play different …

Mechanical alterations in shale formations due to exposure to water-based fracturing fluids
and supercritical carbon dioxide (ScCO 2) significantly affect the performance of shale gas …

Rock is geometrically and mechanically multiscale in nature, and the traditional
phenomenological laws at the macroscale cannot render a quantitative relationship …

A major geological risk factor for engineering and energy-related applications, such as CO 2
storage and unconventional hydrocarbon production, is the geomechanical integrity of …

Organic-rich carbonate mudstones have emerged as a significant unconventional play
globally, particularly the Middle Jurassic carbonate mudstones of the Arabian plate. Despite …

Microscale diagenetic changes that occur during burial exert a profound influence on the
elastic and mechanical properties of sediments—but are poorly quantified. The focus here is …

To investigate the alterations in mechanical properties and damage mechanisms of water-
immersed mudstone, the mudstone from the weak interlayer of an open-pit coal mine in …

The selection of an appropriate mud weight is important in drilling operations, as it plays a
pivotal role in mitigating the potential for costly wellbore instability issues. The safe mud …
