Course Description
This course is designed to develop skills in understanding the geometry and petrophysical characteristics of carbonate reservoirs. Depositional fabric, grain type and size and subsequent diagenetic modifications are the major controls on carbonate reservoir behaviour. The complex inter-relationship of the depositional and burial history can be unravelled to allow prediction of reservoir facies and reconstruction reservoir models.
Course Objectives
- Learning how Carbonates are formed and change through time resulting in the carbonate reservoirs we see today. Participants
- Learning how to identify carbonate facies,
- Understanding the effect of sequence stratigraphy on carbonates,
- Determining the controlling factors for porosity in carbonate reservoirs
