N083: Petrophysics and Formation Evaluation: Principles and Practice

Course Overview
The course examines the fundamental concepts, vocabulary, and techniques used in petrophysics, exploring the physical properties of rock formations and their pore fluids, and demonstrating how these properties are estimated both in the laboratory and the wellbore. It focuses on the key petrophysical ideas that underpin petrophysical analysis and how downhole logs and core measurements enable quantitative estimates of hydrocarbons in place. 

Newly graduated scientists and petrophysicists are the main target audience, together with geologists, geophysicists and engineers who communicate with petrophysicists in regional evaluations, prospect generation and development studies. 

There are no formal prerequisites for this class, due to its introductory nature. Some knowledge of petrophysics maybe advantageous, but not essential. 

Participants will learn to:
•	Illustrate the geophysical parameters, petrophysical core analysis, capillary pressure, and fluid 
        distribution data required for reservoir evaluation.
•	Appraise the nature of the borehole environment.
•	Illustrate how data from the main logging tools is acquired and undertake petrophysical analysis using these data.
•	Establish lithology and calculate porosity from open hole wireline log and core data.
•	Calculate water saturation from open hole wireline log and core data.
•	Establish the key petrophysical parameters from wireline logs.
•	Understand the principles of fluid sampling and borehole pressure measurements as a complementary 
        approach to petrophysical analysis.
•	Define gross, net and pay, and understand how these petrophysical concepts may be applied.
•	Demonstrate how shale content in a elastic reservoir can be estimated and consider the effects of 
        shale on the petrophysical analysis.
•	Illustrate the principle petrophysical differences between conventional reservoirs and unconventional 
        shale gas reservoirs.
