Azeri Central East (ACE) development project


More about the project

  • Next stage of development of giant ACG field in Caspian Sea;
  • The first major investment by ACG partnership under extended PSA;
  • New development approved in 25th year of landmark partnership
The ACE project is the next stage of development of the giant Azeri-Chirag-Gunashli (ACG) field in the Azerbaijan sector of the Caspian Sea. It is a $6 billion development project which includes a new offshore platform and facilities designed to process up to 100,000 barrels of oil per day. The project is expected to produce up to 300 million barrels over its lifetime.
The project was sanctioned in April 2019. The sanction of ACE was the first major investment decision by the ACG partnership following the extension of the ACG Production Sharing Agreement (PSA) to 2049 was agreed in 2017. Around $42 billion has been invested in the development of the ACG area since the original PSA signed in 1994. 
The 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 also includes 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 is 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 ACE platform is designed to use technology innovations and automated operation systems that are controlled remotely from an onshore control room at the Sangachal terminal. It is the first remotely operated offshore platform in the Caspian. Currently, the remote control scope at the Sangachal terminal is 100% complete with the control room already operational allowing testing to take place.
Construction activities for the project commenced in late 2019 and have taken place in-country utilizing local resources. At peak, over 8,500 people were involved in overall construction activities in Azerbaijan. 
Following commissioning and testing activities completions, on 7 August 2023, the topside unit sailed away from the Bayil fabrication yard, where it was built, to the ACG field. 

In the first quarter od 2024, the Azeri Central East (ACE) project made a tremendous progress towards achievement of its main objective – delivery of first oil.
During the quarter the onshore control functionality of the ACE platform was enabled making the facility the first bp-operated offshore platform fully controlled from onshore. The project also completed all required pre-start up activities including the drilling of the first production well spudded in December 2023. The well reached its total depth of 3,150 metres in March and on 16 April, following the completion of all preparations, the project safely delivered first oil from ACE.
