Description

Ce module est la suite du module de Physique des roches de 2ème année. Il a pour principal objectif de présenter comment les avancées récentes dans le domaine de la physique/mécanique des roches permettent d’aborder des problématiques liées à la compaction des réservoirs, au stockage du CO2, à la géothermie, à la nucléation des séismes, aux glissements de terrain et à l’aléa volcanique.
Les thèmes abordés dans le cours sont :

  • les bandes de compaction dans les grès poreux
  • la compaction des carbonates
  • la physique des milieux granulaires
  • la fissuration thermique
  • la plasticité et les dislocations
  • les tremblements de terre profonds
  • les propriétés physiques des roches volcaniques
  • l’électro-sismique

Le module est organisé sous la forme de cours magistraux.

This module is a continuation of the 2nd year Rock Physics module. Its main objective is to present how recent advances in the field of rock physics/mechanics allow to address issues related to reservoir compaction, CO2 storage, geothermal energy, earthquake nucleation, landslides and volcanic hazard.
Topics covered in the course are:

  • - compaction bands in porous sandstones
  • - compaction of carbonates
  • - physics of granular media
  • - thermal cracking
  • - plasticity and dislocations
  • - deep earthquakes
  • - physical properties of volcanic rocks
  • - electro-seismic

The module is organized in the form of lectures.

A la fin de cette UE vous serez capable de :

  • - Interpréter des données de tomographie rayons X sur différents types de roches
  • - Trouver les conditions de formation des bandes de compaction
  • - Interpréter des essais expérimentaux sur des milieux granulaires
  • - Utiliser la théorie de la plasticité
  • - Mettre en œuvre des mesures d’électro-sismique


At the end of this course you will be able to :

  • Interpret X-ray tomography data on different types of rocks
  • Find the conditions for the formation of compaction bands
  • Interpret experimental tests on granular media
  • Use the theory of plasticity
  • Implement electro-seismic measurements

School regulations

The curriculum includes three years of study: admissions, the organisation of studies, assessments, placements and vivas, graduation and international exchanges are all explained in the current school rules (pdf).

First and second year courses

First and second year courses

  • General modules: mechanics, geology, mathematics, IT, digital analysis, signal processing, inverse methods.
  • Geophysical methods: physics of the Earth, seismology, seismic modelling and imaging, geodesy, gravimetry, potential methods, geomagnetism, electromagnetism, rock physics and fracture, hydrology.
  • Practical work: geophysical measurements in the field (photo) and in the laboratory, geology field placements in the Alps.
  • Languages and economic and social sciences: English, modern language 2, economics, industrial property, management, sustainable development, ethics, quality, company health and safety
  • IT and research projects, shared with the first year of the master’s degree
  • Summer placements at a laboratory or company, with numerous opportunities abroad (international placement contact: Mike Heap)

Third year course

Students have a choice of 3 specialisations in the third year:

  • Geophysics applied to the exploration and production of raw materials: seismic and hydrodynamic characterisation of reservoirs, seismic processing and interpretation, potential methods.
  • Geophysics applied to geotechnics: geotechnics and the resistance of materials applied in civil engineering, geomechanics, hydrogeophysics, electromagnetic methods, earthquake.
  • Hydrogeology, hydrogeochemistry, hydrogeophysics (HydroG3).

Additional teaching:

  • Languages and economic and social sciences: English, energy economy, company strategy and structure.
  • Geophysics field camp in Alsace (photo).  Here are images of a normal fault in the Rhine Graben taken by students.
  • 6-month industry placement culminating in the writing of a dissertation and a viva before a jury in order to obtain the engineering degree. The placements are carried out all over the world.
