Prof. Yves Guglielmi, Lawrence Berkeley National Laboratory

"Field-scale Fault Reactivation Experiments by Fluid Injection Highlight Dramatic Aseismic Leakage in Caprock Analogs."

Keynote for the "From lab to field: scaling relationships" theme

Dr. Yves Guglielmi is a research scientist in the Energy Geosciences Division at Berkeley Lab (https://eesa.lbl.gov/profiles/yves-guglielmi/). He holds a PhD from the University of Avignon (France) and, before joining Berkeley Lab in 2016, served as a full Professor of Geosciences and Geomechanics at the University of Aix-Marseille (France). His is an expert on the hydromechanics of fractured and faulted rocks and develops new experimental and modelling methods to improve the understanding of induced seismicity and leakage of faults and fractures. At Berkeley Lab, Dr. Guglielmi leads a research program on induced seismicity across subsurface energy applications, with the goal of developing advanced methodologies for the management and mitigation of induced seismicity. He is the Principal Investigator of several projects in this research area, ranging from unique field-based research with controlled fault activation to the prediction of induced earthquakes. 

Dr Alison Monaghan, British Geological Survey

"At-scale underground observatories for the energy transition"

Keynote for the "Geo-observatories: on-going research on the UKGEOS and other case studies" theme

Dr Alison Monaghan is a principal geologist based at the British Geological Survey in Edinburgh. She currently leads the science delivery of UK Geoenergy Observatory in Glasgow, an underground laboratory focussing on shallow mine water geothermal and heat storage, environmental change, and impact. An experienced project leader, she has worked with Government, commercial companies, and academics on multidisciplinary projects with significant impact. She has a comprehensive knowledge of Carboniferous geology and geoenergy onshore Scotland and offshore UK. 

Dr Adriana Paluszny, Imperial College

"Emerging properties of thermo-chemo-hydro-mechanical coupling in multiple fracture growth simulations."

Keynote for the "Thermo-chemo-hydro-mechanical coupling" theme

Dr Adriana Paluszny is a Senior Lecturer in the Department of Earth Science & Engineering. She has a PhD in Computational Geomechanics from Imperial College London and has served as a Post-Doctoral Research Associate in the Rio Tinto Centre for Advanced Mineral Recovery at ICL, as a Research Fellow funded by EPSRC and NERC and currently holds a Royal Society University Research Fellowship. Her research is primarily focused on the robust numerical modelling of multiple fracture growth in three dimensions, with applications to geomechanical modelling of fluid injection, hydraulic fracturing, rock drilling, effective permeability of fractured rocks, and emerging methods in computational fracture mechanics. She is also interested in understanding how growth is affected by heterogeneities at multiple scales and how the interplay between fluid flow and mechanics affects these interactions.

Dr Anne Pluymakers, Technical University Delft

"Follow the fluid: the potential for fluid-rock interactions in and around a well."

Keynote for the "Energy storage and Energy extraction" theme

The main theme throughout Dr Pluymakers’ research is the effects of fluid-rock interactions on rock mechanical behavior, with emphasis on the mechanical characterization of reservoir-, cap- and fault-rocks. She is fascinated by how rocks break, and how the strength and flow properties of broken rocks evolve - especially in the presence of different – more realistic – fluid types. Dr Pluymakers is at the Rock Deformation lab of TU Delft since 2018, and in 2020 she was promoted to be an assistant-professor in Experimental Fluid-Rock Interactions. From 2015-2017 Dr Pluymakers worked on fractures in shale, including experimental work on CO2-shale interaction at Physics of Geological Processes (now the NJORD center) at Oslo University. Dr Pluymakers has an experimental PhD on the effects of CO2 on the fault mechanics of anhydrite-bearing fault zones from the HPT lab (Utrecht University) since 2015.

Prof. Francois Renard, Oslo University

"How correct are we when calculating fracture properties from X-ray microtomography data?"

Keynote for the "Visualising and quantifying rock deformation and multi-phase flow interactions" theme.

Francois Renard, professor of geosciences at the universities of Oslo (Norway) and Grenoble Alpes (France), is director of the Njord Centre, a cross-disciplinary physics-geology research unit at the University of Oslo. He is developing research on the complex interactions between mechanical forces, fluid flow and chemical reactions, including experimental developments on large synchrotron and neutron facilities.

 Dr Marco Scuderi, Sapienza Universita di Roma

"Linking laboratory with in-situ observations to improve the understanding of fault slip behaviour during fluid pressurisation."

Keynote for the "Subsurface deformation processes: from fracturing to friction and beyond" theme.

After getting his MS at the University of Perugia in 2009, Marco Scuderi moved to The Penn State University for his PhD where he worked in the Rock and Sediment Mechanics Laboratory with Prof. Chris Marone. There Dr Scuderi gained experience in experimental approaches to understand the physical processes at the origin of fault friction, defending his PhD in 2014. After that, he moved to the La Sapienza University of Rome, where, thanks to a Marie-Sklodowska Curie Grant founded by the EU, Dr Scuderi had the chance to focus on the role of fluid pressure in faulting and the origin of fault slip from slow earthquake to seismic events. From 2019 Dr Scuderi is a permanent academic at the La Sapienza University where he is developing a new rock mechanics laboratory.

Dr Alessandro Tengattini, University Grenoble Alpes and Institute Laue-Langevin

"Neutron (and X-Ray) Tomography for Rock Physics and Mechanics."

Keynote for the "Non-destructive testing in rock mechanics and rock physics" theme

Alessandro Tengattini is an associate professor at the 3SR Laboratory, at the University Grenoble Alpes and Chair 'Imaging for Mechanics' Between the University Grenoble Alpes and the Institut Laue Langevin. In the last few years, he developed a Tomograph allowing for simultaneous Neutron and X-ray Tomography named NeXT at the Institut Laue Langevin, in Grenoble. His areas of interest, besides tomography, include the micro-mechanics of cohesive granular media, and micro-to-macro constitutive modelling.
