Participants will learn to

1. Explain the basic principles of formation image log data interpretation, including the purpose and benefits of using different formation image logging tools.
2. Compare the various current formation image logging tools by discussing their theory, applications, advantages, and limitations, as well as strategies for optimizing data acquisition.
3. Describe the process of data loading, quality control, and corrections for formation image logs, including graphical presentation techniques.
4. Identify key features related to borehole shape analysis, including breakouts, tensile fractures, and stress indicators, and classify these features based on their characteristics.
