Top 10 Biggest Oil and Gas Companies in 2025

The global oil and gas industry remains dominated by a few massive corporations that drive energy markets, influence economies, and invest heavily in transition strategies. This article explores the leading companies shaping the sector in 2025, based on production volume, revenue, and market influence.

What Defines the Biggest Oil and Gas Companies?

Size in the energy sector isn’t just about revenue—it includes reserves, production capacity, global reach, and technological innovation. The biggest players often integrate upstream (exploration and extraction), midstream (transport and storage), and downstream (refining and retail) operations. These firms also play a crucial role in advancing carbon reduction initiatives while maintaining energy security. Key indicators include annual production in millions of barrels of oil equivalent (BOE), market capitalization, and annual revenue.
