Course description

A detailed description of the practical techniques of building 3D reservoir geological models will be presented and discussed throughout the course.
To this end specific goals of this course include the development of skills in quality assessment and in interpreting all the input data that are necessary to build a static reservoir model and to understand reservoir features.
The course shows the sequence of processes that lead to the construction of 3D reservoir geological models from  the definition of the 3D geometrical  model to the petrophysical  characterization and to the volume calculation and uncertainty evaluation. The multi –disciplinary nature of the reservoir modeling workflow will be emphasized through the different steps of the modeling.


This course is intended for the disciplines listed below, as well as anyone with a specific interest in the topic. Geologists  and Geophysicists
