Couse description

This short course is vThis 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.ery suitable as a precursor to vendor training. It is aimed at the Instrument Engineer/Technician and the Automation Engineer/Technician.

course objective

At the end of tTo 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.his course the delegate should be able to demonstrate:

  • A solid understanding of the architecture and operation of Distributed control systems (DCS)
  • Ability to design the overall DCS and process control system
  • Better specification of the planned DCS
  • Improved process performance for the plant
  • Understanding of the key ergonomic issues in design of operator displays
  • Apply advanced control strategies  to a plant control system
  • More effective use of your existing DCS process control capabilities
  • Design and create a consistent and effective alarm philosophy for any installation
  • Recognise and deal with human problems when interfacing to alarm systems

course methodology

This training course uses both conventional and non-traditional techniques. It utilises small group and facilitated plenary discussions as well as instruction to explore key concepts, models, tools and techniques. Hands-on exercises and case studies are used to practice the application of knowledge and use of skills. Structured reviews provide the opportunity to consider how the learning can be applied to the delegates’ own work.
