Behind the Hard Hat: Steven Samoil on ML, Reservoir Simulation, and Life Outdoors

YP Spotlight — Dr. Steven Samoil (Behind the Hard Hat)

At a Glance

  • Role: AI/ML Engineer
  • Affiliation: University of Calgary
  • Education: Ph.D. · University of Calgary; M.Sc. Electrical Engineering; B.Sc. Computer Engineering
  • RDTS involvement: RDTS Board member fostering inter-disciplinary associations to accelerate innovation in the energy sector
  • Core interest: ML for reservoir simulation and history matching (including Bayesian optimization and comparisons between classical and quantum computing approaches)
Theme: Using machine learning to accelerate reservoir workflows—without losing sight of physics, engineering judgment, and real-world decision-making.

1) What motivated you to pursue post-graduate studies?

With a background in Computer Engineering, I became interested in reservoir simulation and applied Bayesian optimization to history-matching problems—one key aspect was comparing classical and quantum computing approaches. More broadly, my biggest motivation was a strong drive to learn more about the world around me. Having the opportunity to deeply explore a topic and apply it to real-world problems has been extremely fulfilling.

2) Machine Learning (ML) is a transformational technology. Where do you see it being applicable in Oil & Gas (O&G) operations?

During my Ph.D. research, I directly experienced the benefits of applying ML to history-matching reservoir simulation models. In reservoir modeling, replacing complex nonlinear partial differential equations with high-speed physics-informed ML proxy models can deliver significant gains in speed and performance. In well path planning, applying techniques like path-finding methods to create well paths in static models could improve iteration speed by acting as a filter in low-precision models before moving to methods with higher precision and accuracy. I see this framework as having broad applicability across O&G operations.

3) What do you do for fun?

I enjoy spending time outdoors—skiing, mountain biking local trails, and more recently, long-distance running. The peace of mind that comes from getting out into the wilderness and exercising really helps balance the busy and loud nature of everyday life. And now we have a newborn son, so we’re also experiencing a good new chapter of life!

We ensure the uninterrupted transport of hydrocarbons from the reservoir to processing facilities. Wax, hydrates, asphaltenes, scale, and corrosion can cause flow issues. I use advanced modeling and simulation tools to predict fluid behavior, design and optimize pipeline systems, validate fluid-handling capacities, and develop mitigation strategies for start-up, shutdown, and steady-state operations. This work also involves chemical selection, risk assessment, and operational troubleshooting, all aimed at maintaining safe, reliable, and cost-effective production. Ultimately, flow assurance is critical to both the integrity and profitability of oil and gas operations.

2) What was the topic of your Ph.D.? What motivated you to pursue post-graduate studies? How did it help you prepare for your O&G career?

I focused on understanding the role of wax and hydrate inhibitors in solving flow assurance challenges. In the field visits during my undergraduate studies, I saw the operational difficulties associated with transporting crude oil. At the same time, I gained a deeper appreciation for the critical role energy plays in our collective well-being. This triggered an interest in designing solutions that led to a Ph.D. and subsequently an engineering career in O&G.

3) You must be a cricket fan 🏏 Who is your favorite team?

I love both playing and watching cricket in my free time. My favorite teams are the Indian Men’s and Women’s cricket teams. The game-day atmosphere can be electric, and watching games with friends and family makes it even more exciting.
