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.
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

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.

Design and operating thermal wells is a key part of developing heavy oil field around the world. There are several challenges with thermal well design and consideration to generate and inject steam in heavy and ultra-heavy oil bearing formations. Several projects have successfully implemented thermal recovery around the world with their own unique design and challenges. In this session we hear from the experts from each geographical region on their experience on implementing thermal well design and their challenges and how they overcome their specific challenges. This session aims to promote awareness and Interest through discussion of common and unique challenges in each region.

Early in 2020, many operators in Western Canada had to take drastic measures to control production volumes with negative oil prices. Suspending or shutting-in thermal wells require extensive planning to make sure operations can resume with minimal impact on well health and operation continuity. This session will focus on sharing experiences in regards to the challenges encountered while making these decisions and what kind of analysis were done in order to minimize the associated risks. This break-out session is suggested for engineers working on production, depletion, well servicing, operation and integrity areas.
Getting liner failure wells back online in the most cost effective manner of improving recovery in a low cost environment. Re-entries / redrills are often the most effective method of getting a well back online but often cost significantly more than remediation’s. Improving remediation methods for both completion execution and return to pre-failure rates are keys to their success. This breakout is to dive into the current methods and learning of remediation sand redrills to improve the execution and economics of the jobs.
The toolkit for monitoring wells is fairly broad….DTS fiber for temperature, pressure, temperature, to the more elaborate 4D seismic, acoustic logging, passive seismic, etc. Each comes with a cost, some challenges and reliability. Discussion would include what operators have had experience with, what they wish they had, and experience with some of the emerging technologies.
