The Safaniya oil field, discovered in 1951, is considered the largest offshore oil field in the world. It is located about 265km north of Dhahran in the Persian Gulf, Saudi Arabia, and measures 50km by 15km.
When it was first put into production in 1957, it flowed 50,000 barrels of crude oil per day from 18 wells. Today, the production capacity exceeds 1.2 million barrels per day.
The oil field is operated and owned by Saudi Aramco.
