What you will learn
- Understanding of ancient logs (1932 – 1962)
- How to use these logs to explore in older or poorly developed areas
- Calculations needed to analyze ancient logs
Description
This quantitative course covers the analysis of older logs run prior to about 1962, commonly called “ancient logs”. You will learn skills needed to identify unfamiliar log curves, choose curves that are useful for quantitative analysis, re-scale curves where needed, and obtain reasonable results in the face of missing data. Some specialized methods applicable to ancient logs are provided. Examples and case histories illustrate the topic.
