Well Integrity - Cased Hole Logging and Monitoring

This course teaches you how to monitor and diagnosis wellbore integrity with the aid of cased hole logging tools. You will learn to identify and quantify leak detection, inter-zone cross flow caused by uneven depletion, leaks inside and behind the casing, cement bond quality, establish corrosion monitoring, and verify perforation efficiency.
