Ghawar / Al-Ghawār /الغوار is an oil field located in Al-Ahsa Governorate, Eastern Province, Saudi Arabia. It measures 280 by 30 km (174 by 19 mi), it is by far the largest conventional oil field in the world. The Ghawar field accounts for more than half of the cumulative oil production of Saudi Arabia. It is entirely owned and operated by Saudi Aramco, the state run Saudi oil company.
1948 Max Steineke, was the chief geologist of Aramco at the time of discovery
Start of production
Five production areas:
- Ain Dar
Production and reserves
(Millions of barrels)
- Current production of oil 5,000,000 barrels per day (~2.5×108 t/a)
- Current production of gas 2,000×106 cu ft/d (57×106 m3/d)
- Estimated oil in place 71,000 million barrels (~9.7×109 t)
- Estimated gas in place 110,000×109 cu ft (3,100×109 m3)
- Producing formations Upper/Middle Jurassic, Upper/Lower Permian, Lower Devonian
In April 2010, Saad al-Treiki, Vice-President for Operations at Aramco, stated, in a news conference reported in Saudi media, that over 65 billion barrels (10.3 km3) have been produced from the field since 1951. Treiki further stated that the total reserves of the field had originally exceeded 100 billion barrels (16 km3)
Saudi Aramco reported in mid-2008 that Ghawar had produced 48% of its proven reserves
- Production: 1,665.6
- Cumulative production: 12,542
- Reserves: 70,458
- Total recovery: 83,000
