This course will cover fluid flow in pipes (both single and multiphase flow), the theoretical bases of interpretation of production logging PLT.

By the end of this course delegates will be able to:

• Learn how to look behind pipe or casing to evaluate the formation and its fluids in the near well vicinity
• Understand how to identify downhole fluid movement
• Know the use, limitations and results yield of a variety of production logging tools, including spinner, temperature, noise, fluid injections and other tools as well as the operational considerations
• Learn and understand flow of fluids in vertical and deviated wells
• Know the interpretation of each tool acquired data and how quality is affected by the acquisition process
• Understand the principles on which production log interpretations are based with hands-on examples and an in-class workshop on interpreting Mono and Multiphase flow using production logs
• Gain knowledge on casing integrity problems and cement-casing bond problems and methods of detection
• Learn about time lapse logs and their application to monitor reservoir development during production
