5-Day Log Interpretation
Workshop Summary & Outline

Summary:

This five-day course is designed to provide participants with fundamental principles necessary to understand and interpret open hole logs. The concepts will assist participants to recognize permeability, hydrocarbons and identify rock and fluid types. The session will also include illustrated techniques for recognizing log validity. Participants are encouraged to bring their own logs to complement existing real-life case studies. A complete set of course materials are included. Sessions to analyze logs using spreadsheets will be included. In addition to the usual log analysis properties there will be an introduction to the calculation of in-situ stresses and permeability from logs.
