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.
The primary objective of this course is to help attendees learn about the physics impacting extended reach wells. Attendees will learn about the challenges associated with successfully constructing extended reach wells and deployment of completion equipment and how to use the laws of physics to deploy drill each hole section, successfully deploy tubulars, and analyze residual stresses in the tubulars (compression and twist) once deployed at TD.
- Hole Cleaning Fundamentals
- What factors impact hole cleaning in extended reach wells
- How changing hole size, drill pipe size, flow rate, and fluid properties impact hole cleaning efficiency
- How will hole cleaning time change as wells get longer
- Tripping and Backreaming Fundamentals
- What practices can be used to prevent stuck pipe and NPT while tripping out
- When is backreaming a good idea
- How to backream successfully
- ECD and Surge/Swab Fundamentals
- What impacts ECD and S&S
- Why are ECD and S&S design factors for ER wells
- How to manage ECD and S&S risk from both the design and execution perspective
- Running Casing and Liners in ER Wells
- What mechanisms prevent the casing/liners from getting to bottom?
- Tricks to successfully deploy casings/liners to TD (tubular properties, rotation, floatation, swivels, etc)
- How do the residual stresses within the tubulars impact how production operations are performed?
Tuesday, November 29
This year the organizing committee is endeavoring to provide a greater context for our attendees regarding the near and long term future of the energy business, including both current oil and gas outlooks and the need for the skills / technologies required for the promotion of production assurance and energy security while successfully transition to new energy technologies such as geothermal and CO2 sequestration. Our thoughts are to create a panel for the opening keynote on November 29th that would provide that context through a discussion on the energy future, emerging geopolitics of energy, energy outlook in Alberta and Canada and selected company perspectives.

Geothermal wells , while not unique in other parts of the world, are getting more and more attention here in Western Canada as an emerging alternative energy market. This session will discuss the how to apply the well designs and operations from existing global practices and learnings along with the knowledge of our oil and gas industry in order to create a viable renewable energy industry here in Canada.

Improved and additional monitoring strategies can be a turning point for production optimization which ultimately leads to a reduction in cost per barrel produced. This session focuses on 3 strategies that allow for improved monitoring systems, the first presentation focuses on a strategy to predict and prevent scaling in Geothermal wells through Thermochemical modelling. The second discusses a novel SCVF system on wheels to replace the current monitoring system, the new system is an easy plug in solution that has a significantly reduced footprint compared to the old system. Lastly, we will hear about a low cost option to equip delineation/ OSE wells with temperature and pressure monitoring to provide a more wholistic approach to field production management.

Breakout Session 1: Cased Hole Cement Practices and Challenges
Faciliatator(s): John Runciman, C-FER Technologies and Carl Dyck, Imperial
Description: Participants of this breakout session will participate in a round-table discussion regarding their best practices and associated challenges with cased hole cement and mechanical plug installation and execution during well abandonments. Topics may include (but are not limited to): (i) Lessons learned through difficult abandonment experiences; (ii) Advances in plug technology and installation techniques; (iii) cement additives; (iv) cement plug workstring design; and (v) mechanical plug setting experiences. This breakout session is intended for completions and well integrity engineers, as well as those involved in communicating with, or belonging to, a regulator.
Breakout Session 2: Breaking Limits Not Breaking Liners: Exploring the Limits of SAGD Horizontals and Targets for Production
Facilitator(s): Patrick Nolan, CNRL, Shaista Jivraj, Athabasca Oil, Damien Hocking, Madala and Jesse Stevenson, Variperm Energy Services
This session is directed to those interested in discussing the limits of SAGD horizontals and targets to operate them. Since the beginning of SAGD wells continue to increase in length, and depending on the depths and production expectations, risk and economics result in an effective limit…but that’s changing. New technologies which impact drilling limits, steam distribution and inflow distribution will all be discussed to understand what challenges/solutions are critical for implementing, operating and assessing the benefit of longer wells.

Thermal wells are subjected to a plethora of chemical, temperature, and mechanical damage mechanisms over their lifecycle. Successful monitoring and diagnosis of well damage/failure relies on a variety of technologies and approaches, spanning from the design to operational phase. This session focuses on digital analysis and downhole logging tools that enable drilling, completion, and well integrity engineers to define operating limits, monitor observation well instrumentation, and identify corrosion through concentric casing strings. This session is intended for drilling, completion, and well integrity engineers, as well as associated logging tool and software vendors.

The quest to make thermal operation more economical and reduce GHG emissions requires more innovative well design and completion. Flow Control Devices (FCD) play significant roles in designing better wells, especially as we drill longer wells. In this session, we have three presentations that share some of the field results from the deployment of flow control devices, the lesson learned and performances in the field.

NCG Discussion - Non Condensable Gas Co-injection: Friend or Foe?
Facilitator: Rick Stahl, Strathcona Resources
We all know NCG has it’s benefits, but managing it within a field can be challenging and lead to many issues, therefore in this session we will have an open discussion about NCG practices utilized in industry. The session will poll the audience members on standard practices and will provide a space to discuss and question whether or not NCG is really helping production or inhibiting it.
