What does it take to keep a refinery running when the world won't stop throwing curveballs?

In this episode, Ted Stank and guest co-host Lance Saunders speak with Tom Johnson, VP of procurement at HF Sinclair, an independent petroleum refiner with operations throughout the mid-continent, southwestern and Rocky Mountain regions. Recorded live at the Supply Chain Forum, the conversation pulled back the curtain on one of the more essential and misunderstood industries in the global economy.

Among the topics discussed were why surety of supply—not cost—is the 3 a.m. concern keeping procurement leaders awake, and how the Strait of Hormuz closure and ongoing geopolitical volatility are rippling through petrochemical supply chains in ways consumers never see. Johnson also discussed the crude oil import-export paradox and how refinery infrastructure dictates crude "diets," the rise of data analytics as a seat at the operations table, how tariffs stress-tested supplier relationships and exposed the limits of sub-tier supply chain visibility, and what the skilled trades shortage means for heavy industrial operations.

Johnson is a UT Knoxville SCM alum who has spent his entire career in oil and gas, previously holding roles at Valero and Holly Frontier. He oversees a procurement organization of approximately 100 professionals managing roughly $2 billion in annual spend, including labor, plant inventory, and category management.
