Session THREE - LOGGING TOOL THEORY
Course Outline and Instruction Materials c. 1978 - 2008 E. R. (Ross) Crain, P.Eng.

Integrated Courseware Connecting Logs, Cores, Tests, Productivity, Cash Flow, and Seismic Petrophysics - Since 1973

Students in this class will have varied experience with logs, but need to know how they are run, how they work, how they have evolved over time, and what they are used for. This seminar is supported by "Crain's Logging Tool Theory" (57 pages) reference manual and exercises, a high quality PowerPoint presentation, and 1 day of instruction.

DESIGNED FOR: Anyone who works with logs, or who wants to do more with their logs,
or who works with other people who use logs:

SUMMARY: This non-quantitative course covers all topics needed to understand log data acquisition, logging tool concepts, and basic log analysis concepts.

• Tool Theory – ES logs (64"/16" normal), laterologs, induction, SP, micrologs, sonic, density, neutron, GR.  

• Focusing, or lack of it, on older log suites. 

• Common displays of logs and how to identify each curve.

• How to read logs (e.g. bed boundaries, which log curve is best to use).

• How do the older measurements compare to current measurements, how have these measurements evolved over time – direct comparisons.

• Limitations, common pitfalls (borehole condition. mud system, invasion, mud cake effects).

• Quality control and troubleshooting.
