This course is designed to facilitate the comprehension of the origin, occurrence, movement, accumulation, and exploration of hydrocarbons.
The introduction will recapitulate the knowledge of different types of sedimentary basins and their hydrocarbon potential based on the presence (or not) of source rock.
Sequentially, the following subjects will be discussed:
- Source rock: type of source rock based on different organic matter and depositional environment; TOC
- Maturation: temperature, depth, time and all other variables of the hydrocarbon window of generation
- Reservoirs: occurrences, heterogeneity, dimensions, quality, permeability, porosity
- Migration: fault analysis, relative age of the faults, connectivity between source rock and reservoirs
- Trap/seal: different types of seals (structural and stratigraphic), and the major structures considered exploration targets
- Basic subsurface methods (both seismic and well analysis)
- Different types of oil (light vs heavy) and their use; differences between conventional and unconventional deposits; basic costs; success rate


Compétences visées

Skills :
- Comprehension of different types of source rock
- Understanding the complexity of petroleum systems
- Main exploration targets (based on depositional environments and structures
- Basic notion of costs and success rate in hydrocarbon exploration


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.
