Course description

This course presents practical methods to characterize fracture field and build fracture model. These methods have developed over the past ten years for more than one hundred fractured reservoirs studies. They have performed by different oil companies for different reservoir types and companies around the world.
Upon completion of the course, participants will be able to characterize a fracture reservoir with knowledge on fracture modeling principles. They will develop practical skills to:
•    define different types of fractures
•    identify and analyze fractures from various data (cores, logs, seismic, drilling, well-tests)
•    characterize fracture networks
•    make a synthesis of the fracture analysis, and a develop a conceptual model
•    build a discrete fracture model integrating small-scale and large scale fracture
•    components (joints, fault-related fractures and fracture swarms)
•    Understand principles used for determining fracture length and permeability based on dynamic data analysis.


Reservoir engineers and geoscientists working on fractured reservoirs.
