In the first three quarters of 2025, bp and its co-venturers spent about $388 million in operating expenditure and about $912 million in capital expenditure on ACG activities.

According to bp Azerbaijan, during the third quarter, data acquisition continued for the second year of the 4D high-definition ocean bottom node seismic programme on ACG.

During the third quarter of 2025, ACG continued to safely and reliably deliver stable production. Total ACG production for the first three quarters of 2025 was on average about 327,000 barrels per day (b/d) (about 89 million barrels or 12 million tonnes in total) from the Chirag (21,000 b/d), Central Azeri (88,000 b/d), West Azeri (75,000 b/d), East Azeri (43,000 b/d), Deepwater Gunashli (52,000 b/d), West Chirag (24,000 b/d) and ACE (24,000 b/d) platforms.

On 18 February, ACG celebrated the 20th anniversary of the first oil production from the Central Azeri platform. To date, the platform has produced a total of 1.2 billion barrels (155 million tonnes) of oil.

At the end of September 2025, 145 oil wells were producing, while 48 were used for water and 10 for gas injection.

In the first three quarters of 2025, ACG drilled and completed six oil producer, four water injector and one gas injector wells.

During the first nine months of the year, ACG delivered an average of around 8 million cubic metres per day of ACG associated gas to the state of Azerbaijan (2.1 billion cubic metres in total), primarily at the Sangachal terminal but also to SOCAR’s Oil Rocks facility. The remainder of the associated gas produced was re-injected for reservoir pressure maintenance.

Following the signing of the ACG NAG Addendum in 2024, an initial production well was planned and safely drilled from ACG’s existing West Chirag platform. The well also represents a significant appraisal milestone, as the data obtained will help build future plans for ACG’s NAG development.

In 2025, the well was successfully delivered, providing access to two priority NAG reservoirs - the shallow NKP and the deeper PK reservoirs - both located beneath the currently producing oil reservoirs. It confirmed the presence of gas resources in the NKP reservoir, from which the first ACG NAG production is expected to start in the first half of 2026.

Additionally, the well encountered high-pressure gas in the PK reservoir, where testing is planned for early 2026.
