5 – Visual Log Analysis
What you will learn
The fundamentals of visual log analysis to obtain shale volume, porosity, and water saturation, which are the usual “quick-look” answers that everyone wants to know. You will also:
- Gain an understanding of the visual, or eyeball, log analysis process
- Learn step-by-step procedures for quick-look visual log analysis
- Practice with an exercise and examples
This quantitative course continues coverage of basic petrophysical analysis by investigating what we can “see” by merely looking at well logs, using a few simple rules of analysis. Using Crain’s Rules, a pencil, and a straight edge, you will complete your first log analysis in a very short time, and be able to repeat the process on many more examples over the years ahead. Illustrated step-by-step with a real world example.
- This is course 5 of Crain’s Petrophysics Series. It can be taken independently or in sequence. If you don’t have some background in Petrophysics it’s advised that you take courses 1 through 4 before taking this course.
- Basic understanding of geology is helpful but not required.
- Visual Analysis Basics
- Crain's Rules for Visual Log Analysis
- Visual Analysis for Exercise 1
- Rules for Picking Log Data
- Picking Logs for Exercise 1
