While a variety of logging tools are available to provide information during and after production activities, the majority of log types are utilized to assess the reservoir behavior prior to installing well completion. The several forms of cased hole logging will be covered in this training session, along with how they are frequently utilized to identify production issues and identify corrective measures.

Course Objectives:

At the end of this training course, delegates will learn to:

Distinguish between different types of cased hole logging Tools including its purpose, benefits, and deliverables
Determine the functions of downhole tools used throughout cased hole work with a surface acquisition system
