Azeri-Chirag-Guneshli Oil Field

ACG is a super-giant field located about 100 km east of Baku. It is the biggest producing oil field in the Caspian Sea and covers an area of more than 432 square kilometres.
It lies in water depths of between 120 and 170 metres. The depth of the reservoir is 2,000-3,500 metres.
It is operated by BP on behalf of the Azerbaijan International Operating Company (AIOC)
Oil is exported to the Sangachal Oil and Gas Processing Terminal
There are currently three platforms operating, West Chirag platform, Chirag and Deepwater Gunashli platform
The West Chirag platform has been installed at a water depth of about 170 metres. The design oil capacity of the platform is 183 thousand barrels per day.

The Azeri Central East (ACE) project is centred on a new 48-slot production, drilling and quarters platform located mid-way between the existing Central Azeri and East Azeri platforms in a water depth of approximately 140 metres. The project will also include new infield pipelines to transfer oil and gas from the ACE platform to the existing ACG Phase 2 oil and gas export pipelines for transportation to the onshore Sangachal Terminal.
In addition, there will be a water injection pipeline installed between the East Azeri and ACE platforms to supply injection water from the Central Azeri compression and water injection platform to the ACE facilities.
The project is scheduled for completion in 2023
