Course description

Petrophysics is a key discipline in petroleum exploration and production. The main objectives of this course are to understand:
- The petrophysical properties and corresponding logging methods,
- The fundamentals of log interpretation and formation evaluation,
- The link between petrophysics and seismic reservoir characterization tools


E & P staff with limited background in petrophysics and formation evaluation, beginners in log interpretation.
