Flow-Control-Devices for Thermal Recovery Operations 


Course Description

This 1-day course is an introduction to design and optimization of Flow-Control-Devices (FCDs) in horizontal wells in Thermal Recovery Operations. The interaction between reservoir and FCD, and design charts created to evaluate the response of the FCD are discussed.


  • Different types of the Flow-Control-Devices defining their characteristic curves, and Operating Principles of FCDs.
  • The review of previous use of the Flow-Control-Devices in Canadian SAGD projects: pros and cons.
  • Understanding the critical flow in orifice, venturri and several other types of FCDs.
  • Effects of steam quality on Inflow- Control-Devices (ICD) and Outflow-Control-Devices (OCD).
  • Liquid Pool modeling: a method to calculate the liquid pool level from temperature profile in observation wells will be discussed, and an algebraic equation for liquid pool depletion based on wellbore drawdown, subcool and emulsion productivity is generated and discussed in practical examples. A minimum subcool concept (or target reservoir subcool) is discussed and calculated as a function of skin and pressure draw-down. 
  • Liner-Deployed FCDs modeling: The formulation and physics govern restriction-type (Nozzle and Orifice), frictional-type and several other types of FCDs are presented. The FCD and liquid pool systems are coupled, and pressure drop across the FCD and liquid pool are compared through examples. 
  • Tubing-Deployed FCDs: There will be a presentation on, pros and cons, how to identify wells for tubing deployed FCDs, points to consider and several key design parameters. Examples will be used.

Upon completion of this course, participants will be able to

  • Become familiar with fundamentals of multi-phase flow in pipe
  • Be able to read and understand the FCD characteristic curves
  • Be able to optimize a FCD for a given producer
  • Be able to carry out simple nodal analysis for SAGD producer
  • Become familiar with fundamentals of steam trap control and minimum subcool concept
  • Understanding benefits and limitations of implementation of FCDs for SAGD producer

1 Day

Why Attend

Recently introducing flow control devices (FCDs) as a new method to optimize well operations, there is an extensive need to predict the production performance of SAGD processes considering the production constraints and flow restrictions across chokes and orifices in FCDs. This course presents the fundamentals of liquid pool IPR and FCD flow restriction and their interactions.

Who Attends

Production engineers, reservoir simulation engineers need to model flow control devices (FCDs) in injector and producer, and technology development leaders that are involved in implementation of FCD.

Special Requirements

  • Students will need laptops.
  • Participants should have understanding on one-phase flow such as its frictional pressure calculation.
  • Participants should have basic knowledge of Microsoft Excel.
  • Participants should have moderate experience or exposure to the topic.


0.8 CEUs (Continuing Education Units) are awarded for this 1-day course.
