HF Sinclair

HF Sinclair runs on infrastructure where the blast radius is physical. The independent energy company refines and markets petroleum products across seven complex refineries with an annual average crude oil capacity of roughly 678,000 barrels per day, and it operates midstream petroleum transportation, terminalling, storage and throughput services on top of that. The operating surface spans the Rocky Mountain, Mid-continent, Southwestern and Pacific regions of the United States, plus Canada and the Netherlands, with headquarters in Dallas, Texas. Add a branded retail and marketing operation in the Sinclair Oil brand and the perimeter stops being a neat line - it's refinery control environments, pipeline and terminal logistics, and point-of-sale retail, all under one corporate umbrella.

The company describes itself as organized across five business segments, producing gasoline, diesel fuel, jet fuel, renewable fuels, lubricants, specialty products and asphalt. Employees work across disciplines including refining, petroleum engineering, logistics and midstream operations, data science, cybersecurity, accounting and corporate operations - meaning security work sits alongside the engineers and operators who actually run the plants, not at arm's length from them. Stated priorities include operational reliability, safety, sustainability and responsible growth, under a purpose of safely producing energy products for people and the planet.

For security practitioners, the relevant facts are the asset inventory and the geography: complex refining, midstream throughput and terminalling infrastructure, a marketing brand, and cross-border operations in the U.S., Canada and the Netherlands. That is a threat model that mixes industrial operations with conventional corporate IT and retail, at a scale where downtime is measured in barrels. The team is embedded in a workforce that treats safety and reliability as core operating values rather than slogans.
