Night School – Fractured Reservoirs for Geoscientists and Engineers

Fractured Reservoirs for Geoscientists and Engineers – Session 1 & 2

This course addresses the basic concepts and characterization of naturally fractured reservoir, the importance, potential, and challenges of naturally fractured reservoirs. This will provide practical guidelines for characterizing naturally fractured reservoir, identifying the controlling factors that determine the magnitude of flow in naturally fractured reservoir and analyzing pressure transient in naturally fractured reservoirs using conventional semi-log analysis, type curve matching (commercial software), and direct synthesis method to correctly characterize the reservoir properties. The fracture-dominate flow behavior demands an approach that uniquely differs from the traditional workflow in a conventional reservoir to predict the reservoir performance. It is vitally expedient as an expert in naturally fractured reservoir to demonstrate why and how behavior in conventional reservoirs flow varies from that of naturally fractured reservoir and to identify varying parameters and specific way to process and characterize the uniqueness in this reservoir setting.

Fractured Reservoirs for Geoscientists and Engineers – Session 3 & 4

This course will be based on the mechanisms controlling the genesis of natural fractures, their geometric attributes, special distribution in sedimentary basins, and their contribution to the fluid flow within naturally fractured reservoir. This will provide materials to understand the fracture behaviors in brittle media and characterize fracture types controlling the flow with naturally fractured reservoirs. The material will be including field work, experimental geomechanics tests, statistical analysis of the fractures, borehole imagery logs. This course will give to the students a way of thinking after the first lecture of fracture dataset such as structural maps, isobath maps, core data and log images to have a clear idea about the naturally fractured reservoirs.

• Basic concept of stress and strain
• Relationsheep between stress and fractures
• Tectonic systems in sedimentary basins
• The geometric attributes of the fractures in naturally fractured reservoir
• Special distribution of fractures withing naturally fractured reservoir

Part 4 | 14 July 2022
Facilitator: Abdelmalek Abes, Ph.D. Student
Time: 6:00pm – 8:00pm (BST)

Session 3 & 4
Abdelmalek Abes, Ph.D. Student; University of North Dakota
Abdelmalek Abes, is a geologist with engineering geology background and a Ph.D. student at university of North Dakota. He has received a Bachelor’s degree in Geosciences and Master’s degree in Structural Geology at University of Sciences & Technology, Houari Boumediene in Algeria. He has worked in different geological fields with known structural geologists, such as Dr. K. Amri, Dr. S. Djemai, Dr. H. Fettous, Dr. D. Belhai, and Dr. R. Belkheznaidji.
