Advanced Petrophysics and Formation Evaluation: Istanbul
The course is primarily intended for junior petrophysical staff to augment the skills that they should have already acquired during basic training. The course is also suitable for participants from other disciplines, who wish to have more insight into more advanced petrophysical analysis methods. Such participants should be familiar with basic petrophysical principles and will typically have 2 to 5 years or more working experience in a geoscience or reservoir engineering function.
The course is designed for:
The main emphasis during the course is on practical application rather than extensive discussion around the theoretical background.
The importance of the interaction between seismology, geology, petrophysics and reservoir engineering will be emphasised and illustrated.
All of the topics covered will be accompanied by a relevant exercise, which will be carried out using pre-programmed Excel spreadsheets that mimic the functionality of commercial log interpretation software. All participants will need to provide their own laptop with Excel (v2010 or later).
