Language

Français & Anglais

Audience type

University students in geology or geophysics at Master level. This course will complement their academic university petroleum geology courses, by integrating the whole petroleum evaluation process from the basin regional scale to the prospect scale.

Planned duration

5 half days of about 3 – hours each

Support material

One paper copy booklet (A4 size, with 4 color slides per page) with a selection of the most representative slides. One exercice booklet No digital support provided (eg. on CD or USB key) because problems of data confidentiality.
