Dear Colleagues, 

We are pleased to invite you to submit an abstract to the session EMRP1.7 “Laboratory characterization and numerical modelling of soft rocks” for the next EGU GENERAL ASSEMBLY 2025 which will be held in Vienna from April 27 to May 2, 2025.

The session will be convenered by Maria Lia Napoli (from the Department of Structural, Geotechnical and Building Engineering of Torino Polytechnic) and myself (Chiara Caselle, from the Department of Earth Science of Torino University) and will focus on the laboratory characterization and modeling of the thermal-hydraulic-mechanical-chemical (THMC) behaviour of weak/soft rocks and rock masses.

These rocks represent a challenge in several geoengineering contexts, due to their low strength, high heterogeneity, high proneness to drastic weathering or fracturing processes, and to the fact that they can develop time-dependent and water-interaction-dependent deformations (e.g., creep, swelling, squeezing).

Despite these materials raised big attention in the geotechnical and rock mechanics scientific communities in the last decades, several questions remain open about the understanding of the complexity that drives their behaviour, posing risks to the safety and longevity of infrastructures and to the stability of natural slopes and sea cliffs.

For these reasons, this session proposes to collect contributions about the THMC behaviour of soft rocks and rock masses, welcoming laboratory, modeling and case studies topics, with the objective of revealing our capability of effectively characterizing and predicting the behaviour of these materials. We hope that you wish to contribute to the discussion with your research!  

You can find more information at https://meetingorganizer.copernicus.org/EGU25/session/51719 and the attached PDF.

The abstract deadline is January 15th (13:00 CET)!

We look forward to seeing you in Vienna!

Sincerely, 

Chiara and Maria Lia

The next gathering of the European Geoscience Union – EGU 2025 (Vienna, April 27 to May 2, 2025) will host the session on Petrophysics and Geomechanics for the Energy Transition, convened by Paul Glover (University of Leeds), Wenzhuo Cao (Utrecht University), Daniela Navarro-Perez (University of Southern Chile), Ashley Stanton-Yonge (UCL), Roberto Rizzo Utrecht University) and Eszter Békési (Hungarian Research Network).

Petrophysics and geomechanics have been critical tools in the exploitation of naturally occurring fossil fuels. Now that the world is transitioning away from fossil fuels towards sustainable energy and material sources, these same methods still have critical roles to play. The methods remain the same – it is only their applications that have changed, helping to drive the globe towards net zero and beyond. Conventional petrophysics and geomechanics are being applied to new challenges, ensuring that the wheel does not need reinventing.

The aim of this session is to explore and foster the contribution of petrophysics and geomechanics to improve development of sustainable energy and material resources in the transition to low-carbon energy and net zero.

Papers should show research or deployment involving theory, concept, measurement, modelling, testing, validation of the deployment of petrophysics and/or geomechanics, from/across angström to basin scales, that has the potential for driving us towards net zero, including pore-scale processes that link fluid flow, geochemistry and geomechanical properties, and studies linking petrophysical and geomechanical properties across multiple scales.

Applications include, but are not limited to, (i) carbon capture and storage, (ii) subsurface energy storage, (iii) geothermal energy, (iv) non-carbon gas exploitation (e.g. helium and white hydrogen), (v) wind energy, (vi) hydroelectric energy, (vi) solar energy, (vii) battery storage for smoothing of Intermittent Renewable Energy Sources (IRES). In each case including provision of critical minerals (e.g., lithium, cobalt, neodymium), engineering and groundwater flow are included.

Approaches may include laboratory measurement, field studies, multi-scale imaging, pore-scale and DRM modelling, reactive flow, reservoir modelling, 3D quantification and dynamic simulation, fracture modelling, heat flow quantification and modelling, reservoir integrity cap-rock studies, quantitative evaluation of porosity, permeability or any other properties or approach.

Interested participants are welcome to submit an abstract before January 15, 2025 (13:00 CET).

We would like to invite you and your colleagues to participate in on-line session NP7.1 “Non-linear Waves and Triggering Effects” at European Geosciences Union General Assembly 2024 https://www.egu25.eu.

The session is NP7.1
The deadline for abstracts is 15 January 2025.

Waves in the Earth’s crust are often generated by fractures in the process of their sliding or propagation. Conversely, the waves can trigger fracture sliding or even propagation. Analysis of wave propagation and their interaction with pre-existing or emerging fractures is central to geophysics. Recently new observations and theoretical concepts were introduced pointing out to the limitations of the traditional concepts. These are:
• Multiscale nature of wave fields and fractures in geomaterials
• Rotational mechanisms of wave and fracture propagation 
• Strong rock and rock mass non-linearity (such as bilinear stress-strain curve with high modulus in compression and low in tension) and its effect on wave propagation 
• Apparent negative stiffness associated with either rotation of non-spherical constituents or fracture propagation and its effect on wave propagation
• Triggering effects and instability in geomaterials
• Active nature of geomaterials (e.g., seismic emission induced by stress and pressure wave propagation)
• Mechanics of granular material blowout by gas filtration
• Non-linear mechanics of hydraulic fracturing
• Synchronization in fracture processes including earthquakes and volcanic activity

Complex waves are now a key problem of the physical oceanography and atmosphere physics. They are called rogue or freak waves. It may be expected that similar waves are also present in non-linear solids (e.g., granular materials), which suggests the existence of new types of seismic waves. 

It is anticipated that studying these and related phenomena can lead to breakthroughs in understanding of the stress transfer and multiscale failure processes in the Earth’s crust, ocean and atmosphere and facilitate developing better prediction and monitoring methods. The session is designed as a forum for discussing these and similar topics. 

Best regards,
On behalf of the convener’s team
