Training Course: Sand Control Fundamentals
Ticketed Event
Instructor(s) Mahdi Mahmoudi, Vahid Fattahpour

This course reviews fundamental sand control design for oil development. It goes on to detail the mechanisms, applications, and challenges of various sand control options in both vertical and horizontal applications. It mainly focuses on a practical project requiring the participant to apply what they have learned by selecting, designing, and presenting the most appropriate sand control completion for several case study wells for both cold primary and thermal applications.

Course Topics: 

  • Why Do We Need Sand Control? – Consider the potential impact of sand production over the life of a well and the consequent importance of sand control.
  • Review of Geomechanics and Geoscience: This section reviews the fundamentals of geomechanics and geoscience for heavy oil developments.
  • Corrosion: Review the basics of material selection for sand control and field examples of screen/liner failure due to corrosion.
  • Erosion: Review various erosional models and their application to sand control design, and review of field examples of screen/liner erosion.
  • Plugging: Discuss the plugging mechanism and show examples of different screen/liner plugging from extracted sand control screen/liner.
  • Mechanical Integrity: Discuss various well integrity designs and considerations.

Training Course: Flow-Control-Devices for Thermal Recovery Operations
Ticketed Event
Instructor(s) Mazda Irani

This 1-day course is an introduction to design and optimization of Flow-Control-Devices (FCDs) and to thermodynamics and pressure-volume-temperature (PVT) in horizontal wells in Thermal Recovery Operations for both SAGD and SA-SAGD. The interaction between reservoir and FCD, and design charts created to evaluate the response of the FCD are discussed. The following topics will be covered:

  • 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.
  • Introduction to thermodynamics and pressure-volume-temperature (PVT): basic law such as: Clausius-Clapeyron Equation, Dalton's law, Henry's Law and Raoult’s law are explained and practical examples such as temperature reduction in chamber due to NCG injection, and temperature reduction at Azeotropic point in ES-SAGD process will be solved numerically. 
  • Production Challenges in Solvent Operation: Liquid-pool model and concept will be explained and concern with steam trap control for Nsolv will be discussed and numerically explained. 
  • Effects of Steam quality on Inflow- Control-Devices (ICD) and Outflow-Control-Devices (OCD). 
  • Flashing effect in FCD for both SAGD and SA-SAGD applications
  • 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. 

At the end of this course, participants will be able to:

  • Become familiar with fundamentals of phase behavior modeling 
  • Be able to carry out simple phase-equilibria calculations 
  • 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

Opening Keynote Session - Pandemic Pandemonium – Keeping Wells Healthy During Challenging Times
Moderator(s) Ian Peleshok, Alberta Energy Regulator; Trent Pelke, Suncor Energy
Speaker(s) Steve Spence, Osum Oil Sands Corp.

Throughout the COVID 19 pandemic many thermal and unconventional producers internationally have had to shut in wells for extended periods, operate with a reduced budget, and a reduced workforce capacity. In times of limited capital and people resources, well integrity is not always the highest priority for operating companies. Yet at the same time, we as an industry operate under the world's highest regulatory and environmental standards. This keynote will further explore topics related to the pandemic and well integrity prioritization, industry collaboration, AI and other technological initiatives, ruling governments changing, and the industry rebounding from this pandemic.
