The six-reservoir Manifa oil field measures about 45 kilometers in length and 18 km in width. It lies both onshore and offshore under a relatively shallow 15 meters of water.
It was first discoved in 1957 and was brought onstream in 1964.
Manifa is one of Aramcos biggest fields and has a production capacity of 900,000 barrels a day (b/d).
In July International Oil Daily stated that the Manifa oilfield had been hit by a technical problem that would impact production output.
Sadad al-Husseini, a former executive vice president at Saudi Aramco said that the site was suffering from corrosion problems in the water injection system.
Corrosion control in the water injection system is not a technical challenge but it can be expensive to repair the water injection lines, he said.
