SEMINAR OUTLINE:  LOGGING TOOL THEORY

"50 Years Of Continuous Petrophysical Experience, At Your Service"

 

COURSE SUMMARY
This non-quantitative course covers all topics needed to understand log data acquisition, logging tool concepts, and basic log analysis concepts for both open and cased hole logs.

  • Basic Physics and Basic Operating Concepts – ES logs, laterologs, induction, SP, micrologs, sonic, density, neutron, GR. NMR, TDT,

  • 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).

COURSE DURATION
1 day - 8 Professional Development Hours (PDH)

COURSE LEVEL
Beginner to Intermediate.
