🔬 From Lab Chips to Oilfields – with Stuart Kinnear – CEO of Interface Fluidics
In this episode “Microfluidics with Stuart Kinnear for the Excel or Routine Podcast”, I chat with Stuart Kinnear, co-founder and CEO of Interface Fluidics. Stuart shares the story behind Interface and what it is like to lead a high-tech company in oil and gas! We talk about:
– What microfluidics is (and why it matters)
– Real stories from oilfields using new testing tools
– Polymer floods, frack fluid cleanup, waterflood problems
– The future of fluid testing in oil & gas and beyond
We also dig into what it’s like to build a startup, work with companies like Equinor, and where this technology is headed next.
👉 If you’re into energy tech, innovation, or just love a good founder story, this one’s for you.
About Interface Fluidics
Interface Fluidics is a Canadian technology company revolutionizing fluid analysis in the energy sector through advanced microfluidic solutions. Founded in 2015 and headquartered in Edmonton, Alberta, the company specializes in high-pressure, high-temperature testing that delivers rapid, accurate insights into fluid behavior under extreme conditions.​
At the core of Interface Fluidics’ innovation is SapphireLab, a proprietary platform that miniaturizes and accelerates fluid testing processes. This system enables energy companies to conduct critical analyses—such as PVT (Pressure-Volume-Temperature) modeling, miscibility determination, and flow assurance—more efficiently and cost-effectively than traditional methods. By simulating reservoir conditions at the pore scale, SapphireLab provides real-time data that enhances decision-making in areas like Enhanced Oil Recovery (EOR), hydraulic fracturing, and carbon capture and storage (CCS) initiatives.​
Interface Fluidics’ technology has been validated across major energy markets, including North America, the Middle East, and offshore operations. Their approach not only reduces laboratory costs and testing times but also supports the industry’s transition toward more sustainable practices by optimizing resource utilization and minimizing environmental impact.
