Production Logging Training Course

This short course introduces basic concepts used for production logging in vertical wells and progresses to more complex cases of highly deviated and horizontal wells, explaining the application, limitations and evolution of the different sensors used in the PL services. Most importantly, the course empowers the attending delegates to tailor data acquisition programs selecting the best set of sensors depending on fluids being produced, well deviation, completions type and objective of the log. The discussion of the response and quality control of each sensor is used to guide the attendees on the process of interpretation, starting from individual sensors and evolving to the combination of two or more sensors to determine fluid type and its quantitative contribution by each of the producing intervals. This short course is illustrated with practical exercise after each topic and quizzes at the end of each day to help the attendees absorb and retain the important concepts of each day and to help the tutor gauge the progress as course progresses.

To introduce the principles, applications, techniques and procedures for production logging (PL), including limitations and optimum configuration of the different sensors used for the production logging. The aim is also to help professionals with functional role or interest in this area to use PL proactively and to use the well information to design and plan data acquisition as part of the solution to flow assurance, well integrity and diagnosis.

Engineers in exploration, production and completions departments; reservoir, production, well integrity and flow assurance engineers, petrophysicists.
