2 – Logging Tools – Resistivity
What you will learn
- Basic physics and basic operating concepts.
- 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).
- Limitations, common pitfalls (borehole condition, mud system, invasion, mud cake effects).
This course continues coverage of basic petrophysical analysis with a review of logs used to determine resistivity or correlation of rock formations.
Tools are described in their generic form and specific service companies may offer variations on the basic design concepts.
Knowledge of tool theory is especially important when things don’t appear to be “going right”. Many log analyses fail because the tool’s limitations or operating environment were exceeded. You need to know when and where the data will be valid.
- Basic understanding of quantitative Petrophysics or equivalent background.
- Basic understanding of high school level physics is helpful but not required.
- Electrical Survey
- Spontaneous Potential
- Induction Logs
- Micrologs and Microlaterologs
- Gamma Ray Logs
- Caliper Logs
- Thermal Decay Time Logs
Target AudienceThose who wish to become proficient in petrophysical analysis or who need to manage or make use of petrophysical results will benefit from this course, including:
- Log analysts,
- Reservoir engineers,
- Completion engineers,
- Stimulation engineers, and
- University / Tech school students
