Intermediate Production Logging and Reservoir Monitoring
This course provides you in-depth instruction on cased hole logging tool physics, interpretation, and quality control techniques applied to wellbore specific production logging and reservoir monitoring scenarios. You will learn how and when to use these tools for your specific logging objectives including applications to three phase flow measurement. You will also learn quick look techniques for identifying quality control problems with existing logs. Using hands-on examples, you will learn to interpret behind casing resistivity and measuring three phase flow using production logs.
