2 – Logging Tools – Resistivity

$99.00

This course continues coverage of basic petrophysical analysis with a review of logs used to determine resistivity or correlation of rock formations.

You will learn the basic physics and operating principle behind each tool, the common log displays, and limitations of each tool.

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.

Who Should take this course:
Managers, geologists, log analysts, geophysicists, reservoir engineers, completion engineers, stimulation engineers, and university / tech school students who wish to become proficient in petrophysical analysis or who need to manage or make use of petrophysical results will benefit from this course.
