Microcracks in rock (Petrology 💎)

Microcracks in rock, also known as microfractures and cracks, are spaces in rock with the longest length of 1000 μm and the other two dimensions of 10 μm. In general, the ratio of width to length of microcracks is between 10−3 to 10−5. Due to the scale […]

Integrating Fault Stability and Stress Analysis in Ethiopian Rift Geothermal Field The Tulu Moye geothermal field in the actively deforming Main Ethiopian Rift presents substantial potential for renewable energy production, but interactions between fault systems, hydrothermal fluids...

This study provides a key framework for assessing fault stability and managing risks in active geothermal systems.

The work is now under review @commsearth.nature.com

4/12 WHY COULDN'T THIS BE PREDICTED?

Dr. Davide Elmo (UBC): "Looking at a rock face from outside doesn't show what's happening inside."

"We know rockfalls will happen. We don't know when."

"That kind of rockfall cannot be stopped."

Stress–strain hysteresis during hydrostatic loading of porous rocks A micro-mechanical model is proposed to predict the stress–strain hysteresis during the cyclic hydrostatic loading of fluid-saturated rocks under drai…

Have you ever wondered how the stress-strain curve of an isotropic rock, subjected to a pure isotropic confining pressure, can exhibit hysteresis while remaining within the pure elastic regime?
If so, check out my latest paper.

So after a long absence due to maternity leave, back with a bang!Super proud of this interview with Universiteit van Nederland on #rockmechanics for #CCS and the #energytransition (for all internationals, youtube provides reasonably good English captions) youtu.be/lNKib4gbcQc?...

Fixing hydraulic leaks it is always a lot of fun 🤔
