Oil companies in Greater Houston cluster around six key districts. Here's where to find them — and who's there.
The Energy Corridor, stretching along I-10 between Highway 6 and Barker Cypress Road, is the epicenter of Houston's oil industry. Major tenants include BP America, ConocoPhillips, and dozens of midsize E&P firms. Over 90,000 energy workers commute here daily.
Houston's central business district houses iconic energy skyscrapers including the Chevron Tower, LyondellBasell Tower, and NRG Center. Many trading desks and corporate finance teams operate from premium downtown office space.
North of Houston, The Woodlands and Spring are home to ExxonMobil's 385-acre campus — the largest corporate campus in the Houston metro. Anadarko's former campus (now Occidental) and numerous service companies also operate here.
The Westchase District near the intersection of Westheimer and the Sam Houston Tollway is a secondary hub for oilfield services and engineering firms. Many international NOCs and IOCs maintain regional offices here.
The 52-mile Houston Ship Channel connects Houston to the Gulf of Mexico and is lined with the densest concentration of refineries and petrochemical plants in the Western Hemisphere. Over 700 million barrels of crude are processed here annually.
The rapidly growing Katy and West Houston corridor has attracted numerous energy companies seeking modern campuses with lower costs. Academy Sports' energy neighbor companies and many pipeline operators call this area home.

Houston's dominance as the global oil capital traces back to the 1901 Spindletop gusher in nearby Beaumont. That single discovery created the modern petroleum industry and attracted a wave of wildcatters, engineers, and financiers to Southeast Texas.
Today, the advantages are self-reinforcing: Houston offers the deepest talent pool in energy, a world-class port (the Houston Ship Channel handles 247 million tons of cargo annually), no state income tax, and the unmatched network effects of having thousands of energy firms within a 50-mile radius.
The Energy Corridor alone concentrates more oil company headquarters per square mile than any other district on Earth. Companies locate here because their partners, competitors, suppliers, and customers are all within a short drive.
Houston is also leading the energy transition — major oil companies here are investing billions in carbon capture and storage (CCS), hydrogen, and offshore wind. The city's energy expertise is evolving, not disappearing.
