5 days REE/INFORES
- Managers, engineers, technicians and Oil & Gas industry staff facing day-to-day Reservoir Engineering concerns: geoscientists, geo-information engineers, drilling/completion engineers and technicians, petroleum engineers, production engineers and technicians, economists etc.
- This course provides participants with a general understanding of main Geosciences & Reservoir Engineering concepts and related data used in Oil & Gas fields development projects and the way these data are integrated.
- Upon completion of the course, participants will be able to:
- describe the main steps of Oil & Gas fields exploration and development process,
- describe petroleum systems, reservoir rocks and related fundamental properties and related techniques to get relevant information (core analysis, logs, well testing),
- describe reservoir fluids and related fundamental properties,
- describe main reservoir production mechanisms and related expected performance,
- discuss the concept of reserves and the related concepts of uncertainties and economics criteria,
- discuss how these data/concepts are used by multidisciplinary teams within field development projects.
- No prerequisites for this course.
