Abu Dhabi National Oil Company (Adnoc) has awarded a $489 million engineering, procurement and construction contract to Greek player Archirodon Construction Overseas to upgrade its Bab onshore field.

Adnoc said in a statement the contract would involve building “the facilities and infrastructure required to sustain long-term crude oil production capacity” from the Bab field to 485,000 barrels per day.

Bab is one of the largest producing onshore oilfields in the United Arab Emirates.
