Applied geophysics


ECTS Credits : 2

Duration : 21 hours

Semester : S8

Person(s) in chage :

Judith SAUSSE, Professor,

Keywords : Geophysics, petrophysics, seismic methods, electrical methods, wells geophysics


Prerequisites : None

Objective: First approach to the main geophysics methods used in the geotechnical, mining and petroleum sectors

Program and contents :

Geophysics is a both fundamental and applied science that allows to describe the physical properties of rocks and natural materials thanks to the common and standardised methods that will be presented throughout this course. The natural environment, the rocks and minerals on which they rely are of different sorts in terms of chemical, mineralogical and petrophysical compositions: texture, porosity, permeability and fluid contents that modify the physical properties of rocks collected during geophysical prospecting.

In the petroleum industry, in hydrogeology and in the mining industry, this physical response is commonly represented as diagraphies, physical measures carried out compared to the depth of the borehole. The main diagraphic tools, technical completion of oil wells, their calibration and the implementation and interpreting of diagraphical measures will be presentend. This one-dimensional exploration of depth per well is often completed by 2D and/or 3D campaigns relying on seismic or electrical methods. These methods will first be presented from a theoretical point of view then inversion methods using specialised computer tools will be used.

A fieldwork class towards the end of the course will make the practical use of seismic and electric tools possible.



Description and operational verbs


The main concepts of petrophysics, rocks as a natural materials.
The most common geophysics methods and their applications. The typical vocabulary of reservoir engineers.


The relationship between rocks' petrophysical and geochemical properties and their response to geophysic tools.


The concepts seen in class to case studies


Be capable of quickly analysing a map, a geophysical profile coming from a geophysical prospection campaign and infer the physical and chemical properties of rocks.


Be capable of deciding what geophysical methods are needed to complete a given prospecting (large scale, below ground level, mineralogical and energetic resources)
