5 days REE/CONSCAL
- Reservoir engineers, petroleum engineers and experienced technicians willing to deepen their knowledge in petrophysics and core analysis.
- This course provides information on how rock properties impact the reservoir description and the flow dynamics and how to get them from core analysis.
- Upon completion of the course, participants will be able to:
- explain and discuss the use of petrophysical properties for reservoir static and dynamic description,
- describe and explain how rock properties are obtained from core analysis,
- describe laboratory equipment, data acquisition and data processing for each property measurement.
- No prerequisites for this course.
Ways and means
- Hands-on practice through real lab experiments carried out during the training.
- CYDAR™ software is used to design and interpret the experiments and to perform additional exercises.
