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

·         Learn  how Carbonates are formed and change through time resulting in the carbonate reservoirs we see today. Participants 

·         Learn how to identify carbonate facies, 

·         Understand the effect of sequence stratigraphy on carbonates, 

·         Determine the controlling factors for porosity in carbonate reservoirs
