Diplôme d'ingénieur de l'École et observatoire des sciences de la Terre (EOST)Parcours Diplôme d'ingénieur de l'EOST


Ce module est la suite du module méthodes potentielles et électromagnétisme de 2ème année. Il a pour principal objectif de donner les bases nécessaires à l’interprétation des données, et s’appuie sur des cas d’études réels, et des traitements avancés.
Contenu du cours
Méthodes potentielles en exploration : anomalies magnétiques ou gravimétriques dues à des structures à trois dimensions en domaine spatial et spectral, les opérateurs de traitement de cartes et sur l’interprétation de grilles aéromagnétiques ou gravimétriques (levés industriels).
Prospection électromagnétique en domaine diffusif, TDEM, CSEM et Magnéto-tellurique. Des jeux de données réels sont manipulés.
Prospection géoradar, rappels sur la théorie EM à haute fréquence, et études de cas.

This module is the continuation of the potential methods and electromagnetism module of the 2nd year. Its main objective is to give the necessary bases for the interpretation of data, and is based on real case studies and advanced treatments.
Course content
Potential methods in exploration: magnetic or gravimetric anomalies due to three-dimensional structures in spatial and spectral domains, map processing operators and the interpretation of aeromagnetic or gravimetric grids (industrial surveys).
Electromagnetic prospecting in the diffusive domain, TDEM, CSEM and Magneto-telluric. Real data sets are manipulated.
Georadar prospecting, reminders on high frequency EM theory, and case studies.

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.
