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

Thermal wells exposed to conditions that will deform casing due to thermal-mechanical forces and geomechanical impacts. This session will show some of the new tools and technologies used to 1) quantify the amount of strain casing is being exposed to during thermal service, 2) detect deformation of casing and tubing to understand the risk of loss of wellbore access and loss of integrity, 3) understand the impact of impairments on the casing caused by thermal service. This session is intended for completion, well integrity and production engineers as well as vendors that are in logging and well servicing industry.

Join us for an in-depth discussion on Surface Casing Vent Flows (SCVF) in thermal wells. We will start the session with data and insights from the regulatory on SCVFs. We will then invite a panel of industry experts to discuss how they detect, verify, repair and monitor SCVF in their operations. We will be seeking opinions from the experts on tried-and-true methods of detection, timing of repair, repair techniques and insights to new technology that may assist with SCVFs. Audience participation is welcome in this session with questions and their own experience and insight.

Topic 1: Sands, Clays & Scale, Oh My!: Discussing a Variety of Chemical Stimulation Treatments on SAGD Wells
Room: Cascade Ballroom
This session is directed to those interested in discussing chemical stimulation treatments on SAGD producer wells. With operators looking at how to get more out of their existing wellbores, the use of chemical stimulation treatments are being used to mitigate sand and scale limitations. Through interactions between operators, service providers, and chemical stimulation experts, this session will provide an introduction to conditions wellbore chemicals may treat, how best to plan a treatment workover, and troubleshooting recommendations for flow back to minimize impact to the processing facility. The hope for the outcome of this session is to come away with new insight into the treatment or reduction of clays, scales, and sands in your wellbores as well as the steps to plan and execute chemical stimulation workovers from the wellhead to the plant inlet.
Topic 2: Thermal Compatibility
Room: Ivor Petrak Room
In addition to the steam injection and bitumen production wells in thermal assets, there are other wells in thermal areas that were drilled before even thermal EOR techniques were developed. Integrity of those wells needed to be verified and confirmed through thermal compatibility process. Purpose of this break-out session is to discuss the thermal compatibility assessment process and how each operator handles it from organizational and operational perspectives. Moderators will provide questions to audience with the purpose of understanding the challenges and opportunities to streamline thermal compatibility assessment among peers to gain alignment and unified approach.
Topic 3: Well Design and Operation
Room: Alhambra Ballroom
Join us for a breakout session that will explore thermal wellbore design and operation under various reservoir scenarios. Through thoughtful questioning, we will collaborate with leading thermal professionals and service providers to discuss wellbore design best practices, designs for tough reservoirs and go over technology that can aid with optimal SAGD production. This session will provide you with valuable insights on designing, deploying, and operating the most cost-effective and efficient SAGD liners in Western Canada's toughest conditions.
