CDGA

Carbonate reservoirs are considered to be the most significant source of hydrocarbon production for this century. This course is offered to provide an introduction to carbonate reservoir evaluation through use of academic and industry course material. Basic terminology and concepts will be taught through lectures, group work and self study assignments: the geology and diagenesis of carbonates, sequence stratigraphy, Petrophysics and seismics in carbonates and basic reservoir engineering and well testing. Examples of different carbonate reservoirs will be used to demonstrate the importance of integrating engineering and geoscience data and understanding in effective reservoir management. Reservoir characterization involves the understanding and methods used to characterize reservoir heterogeneity. This course provides a special focus on carbonate reservoir properties in constructing realistic 3D images of its geological and petrophysical properties. The course covers an extensive amount of case studies from various geological fields. This will also provide methods in the predicting reservoir performance in an integrated approach through reservoir geology, Petrophysics, and reservoir engineering.

The Training Course Will Highlight ?

This course aims to give participant an overview of the carbonate reservoir characterization process. At the end of this course, the candidates should be able to classify carbonate rocks, interpret depositional systems and components and their implications for reservoir rock quality and distribution, understand basic diagenetic processes and their influences on reservoir properties and porosity distribution, Understand and apply carbonate seismic stratigraphy and sequence stratigraphy, understand carbonate rock type and rock type distribution, and finally have a basic knowledge of the workflow to build 3D reservoir model.

Training Objective
