Ghawar Field

Ghawar (Arabic: الغوار) is an oil field located in Al-Ahsa Governorate, Eastern Province, Saudi Arabia. Measuring 280 by 30 km (170 by 19 mi) (some 8,400 square kilometres (3,200 sq mi)), it is by far the largest conventional oil field in the world, and accounts for roughly a third of the cumulative oil production of Saudi Arabia as of 2018.

Ghawar is entirely owned and operated by Saudi Aramco, the state-run Saudi oil company. In April 2019, the company first published its profit figures since its nationalization nearly 40 years ago in the context of issuing a bond to international markets. The bond prospectus revealed that Ghawar is able to pump a maximum of 3.8 million barrels (600,000 m) per day—well below the more than 5 million barrels (790,000 m) per day that had become conventional wisdom in the market.
