Course Objectives
The overall objective of the course is to provide the student with basic understanding of the petrophysics of petroleum reservoirs; and expand his/her ability to perform quantitative calculations related to fluid storage capacity and fluid-flow performances of reservoirs. Specific objectives are:Learn the nature of a petroleum reservoir, reservoir forming rock types and their petrographic properties, geological processes that affect rock properties and fluid contents; sampling and testing methods and temperature and pressure effects on reservoir properties.
Course Content
Petrophysical properties of reservoir rocks and measurement procedures: Coring and core handling; sandstone and carbonate reservoir rock and pore types; fundamental porosity, grain density, permeability and saturation properties; special core analysis such as mechanical, acoustic and electrical properties; multiphase rock and fluid interactions, interfacial tension, capillary pressure, wettability and relative permeability properties.
Course Learning Outcomes
Upon completion of this course, the student should be able to:
1. Recognize reservoir forming (sandstone and carbonate) rock types, their textures and pore structures
2. Handle and prepare cores according to standard core handling procedures
3. Define porosity, discuss the factors which effect porosity, and describe the methods of determining values of porosity.
4. Define the coefficient of isothermal compressibility of reservoir rock and describe methods for determining values of formation compressibility.
5. Reproduce the Darcy equation in differential form, explain its meaning, integrate the equation for typical reservoir systems, discuss and calculate the effect of fractures and channels, and describe methods for determining values of absolute permeability.
6. Explain boundary tension and wettability and their effect on capillary pressure, describe methods of determining values of capillary pressure, and convert laboratory capillary pressure values to reservoir conditions.
7. Describe methods of determining fluid saturations in reservoir rock and show relationship between fluid saturation and capillary pressure.
8. Define resistivity, electrical formation resistivity factor, resistivity index, saturation exponent, and cementation factor and show their relationship and uses; discuss laboratory measurement of electrical properties of reservoir rocks; and demonstrate the calculations necessary in analyzing laboratory electrical measurements.
9. Differentiate permeability, relative permeability, reproduce typical relative permeability curves and show effect of saturation history on relative permeability; illustrate the measurement of relative permeability; and demonstrate some uses of relative permeability data.
10. Demonstrate the techniques of averaging porosity, permeability, and reservoir pressure data.
