SLB vs Halliburton: Which Is the Better Buy in 2026?

The geographic revenue split defines the competitive comparison. SLB earns roughly 80%+ of revenue internationally — Middle East, Europe, Africa, and Latin America where national oil companies drive long-cycle infrastructure investments. Halliburton earns a higher proportion of revenue from North American shale, where independent US producers drive short-cycle drilling decisions that can change quarter to quarter based on oil prices and capital discipline. Different budget holder types, different contract lengths, different revenue predictability.

SLB's international revenue mix gives it exposure to the multi-year Middle East, Latin America, and offshore infrastructure buildout that Halliburton's North American concentration partially misses. International oil companies are in an extended capex upcycle as national oil companies in Saudi Arabia, the UAE, and Brazil invest in production capacity — SLB's digitalization and reservoir performance services are better positioned for those markets. Halliburton's North American shale exposure is a feature in US production booms but a liability when shale drillers cut spending. SLB for the international long-cycle bet; Halliburton for the North American shale cycle.
