Output from Saudi Aramco's massive Manifa oilfield has been hit by a technical problem, the International Oil Daily has reported, citing unnamed sources.

Manifa is one of the Saudi oil giant's biggest oilfields and latest expansions, with a production capacity of 900,000 barrels per day. Aramco brought the field online in two phases.

The industry publication reported that it was unclear how much production was removed, as a result of corrosion of the water injection system used to maintain pressure in the reservoir.

It added, quoting sources, that the losses were likely to be in the "millions of dollars".

"Corrosion control in the water injection system is not a technical challenge but it can be expensive to repair the water injection lines. They will probably have to shut down the field for maintenance," said Sadad al-Husseini, a former executive vice president at Saudi Aramco told the International Oil Daily.

"It may have an impact on maximum sustainable capacity but will not affect Aramco's share of exports," said Husseini, now an energy consultant.
