Verticals

Overview

National & Integrated Oil Companies covers the vertically-integrated majors that span exploration, production, refining, and marketing — in the U.S., the supermajors ExxonMobil and Chevron, alongside the U.S. operations of global majors (Shell, BP, TotalEnergies). They combine upstream production with downstream refining and chemicals at enormous scale.

Demand and strategy are driven by integration (capturing margin across the value chain), scale, and increasingly the navigation of the energy transition (the U.S. majors emphasizing oil and gas plus low-carbon ventures, versus European majors' faster pivot). The majors are leading the consolidation wave (ExxonMobil–Pioneer, Chevron–Hess). It is highly consolidated, capital-intensive, and globally integrated.
