Rock and Fluid Properties

At the end of this course, the students should be able to: 1. recognise reservoir forming rock types (sandstone and carbonate), their textures and pore structures; 2. handle and prepare cores according to standard core handling procedures; 3. define porosity, discuss the factors which affect porosity, and describe the methods of determining the values of porosity; 4. explain the thermodynamic behaviour and phase equilibria of reservoir rock and fluids; 5. describe methods of determining fluid saturations in reservoir rock and show relationship between fluid saturation and capillary pressure; 6. demonstrate the techniques of averaging porosity, permeability and reservoir pressure data; 7. appreciate the chemical and physical properties of the different reservoir fluids; 8. use reservoir phase behaviour to analyse reservoir fluid characteristics; and 9. explain fundamental concepts in the determination and evaluation of fluid properties.
