Tenaris is the world's largest manufacturer of steel pipes for the oil and gas industry — supplying the casing and tubing that lines every oil well drilled globally. When oil companies cut drilling programmes because Brent is below $50/barrel, Tenaris faces sharp volume declines. When Brent recovers, drilling activity surges and Tenaris captures both volume and pricing recovery.
Why Brent Drives Tenaris
Tenaris sells oil country tubular goods (OCTG) — the steel tubes used to drill and complete oil and gas wells. Every new well requires kilometres of casing and tubing; every well workover requires replacement pipe. When Brent falls below $50/barrel, oil companies cancel drilling programmes and OCTG demand collapses. Tenaris faces both volume decline and price compression as the global pipe inventory overhang builds.
Tenaris has a unique competitive advantage: it is one of the very few OCTG producers with global manufacturing scale (plants in Argentina, Mexico, Romania, Italy, Canada and the US), allowing it to serve any major oil basin at competitive cost. This scale creates resilience at cycle troughs that smaller regional competitors lack.
The 2020 Cycle: +107% in 27 Months
COVID-19 sent Brent below $20/barrel and global drilling activity fell 60% in 2020. Tenaris fell to €7. As Brent recovered and drilling activity rebounded — particularly in the US shale basin and Middle Eastern national oil companies — Tenaris reached €14.5 by June 2022. A gain of 107% in 27 months, closely tracking Subsea 7 (+130%) and OMV (+108%) in the same Brent cycle.
Key Risks
Tenaris's main risk is the energy transition — as oil drilling activity structurally declines over the coming decades, demand for OCTG will fall. The company is investing in premium connections and heat treatment technologies that reduce the impact of volume decline through higher per-unit pricing. Its strong position in offshore drilling (where wells require premium pipe products) provides some insulation from the shale drilling cycle.
