Saudi Aramco is not a single refinery, but rather the world's largest integrated state-owned oil and gas producing corporation, managing vast upstream extraction networks alongside extensive domestic and international refining joint ventures. While Aramco operates or holds stakes in several of the largest and most advanced refining complexes globally—such as the massive Jamnagar refinery complex in India or major facilities in Saudi Arabia—individual mega-refineries elsewhere occasionally rival or exceed single-site processing capacities depending on configuration and regional output metrics.
