Overview of Pure-Solvent and Steam-Solvent Analysis and Design for Thermal In-Situ Operations
Training Course Description
This 1-day course is an introduction to thermodynamics and pressure-volume-temperature (PVT) and tuning parameters to fit laboratory data. Different analytical models for oil rate predictions such as Butler-Mokrys (1989) and Dunn-Nenniger-Rajan (1989) models will be discussed. The following topics will be covered:
- 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.
- Pure Solvent Modelling: processes such as VAPEX and Nsolv will be explained, and different theories explaining the pure solvent oil rates such as Butler-Mokrys (1989) and Dunn-Nenniger-Rajan (1989) models will be explained and compared to physical models. Concepts such as onset of asphaltene precipitation will be discussed.
- Steam-Solvent Modelling: ES-SAGD process will be explained and Gupta-Gittins(2012) and Rabiei–Harding–Abedi (2017) models will be discussed and numerically compared.
- 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.
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
- Assumptions made in solvent analytical models for oil rate prediction
- Understanding benefits and limitations of pure-solvent and steam-solvent processes
SAGD is an energy-intensive process with large amount of greenhouse gas (GHG) emissions and required water treatment. One option to reduce emissions and water treatment are solvent recovery techniques such as Solvent Driven Process (SDRP), expanding-solvent SAGD (ES-SAGD) and Nsolv processes. Such processes aim to use thermal and compositional mechanisms to increase the mobility of the bitumen-rich phase near the chamber edge. This course presents the fundamentals of these technologies and also provide an intermediate level understanding of PVT analysis and modeling of such processes.

Mazda Irani is a senior reservoir engineer at Suncor Energy. He is currently engaged in designing and optimization of Steam Assisted Gravity Drainage (SAGD) and Enhanced Solvent Extraction Incorporating Electromagnetic Heating (ESEIEH). ESEIEH is a new in-situ oil sands recovery process that uses radio frequency waves other than steam for heating the reservoir. Mazda holds a PhD and three MSc degrees and currently pursuing his studies for his second PhD in university of Calgary. His PhD is focused on understanding instability at the edge of SAGD steam chamber. Before joining Suncor Energy he worked with RPS Energy (APA) and C-FER Technologies. He has published and presented more than 30 technical papers on different aspects of SAGD operation. He has developed various analytical solutions and proxies for different aspects of SAGD operation, which currently have been used in Suncor assets.
