BAKU, Azerbaijan, November 4. In the first
three quarters of 2026, bp and its co-venturers spent about $401
million in operating expenditure and about $1.088 billion in
capital expenditure on Azeri-Chirag-Gunashli activities, bp said in
its business update.


As such, the operating expenditure rose by 3.35 percent from
$388 million in the first three quarters of 2025, while the capital
expenditure increased by 19.3 percent from $912 million in the same
period in 2025.


“During the third quarter, the 4D high-definition ocean bottom
node seismic programme on ACG continued with the interpretation and
integration of the data acquired in 2025. In parallel, preparations
advanced for the third year of data acquisition, which is scheduled
to commence in January 2027,” said the company.


bp noted that in the third quarter, the multi-well subsea
intervention campaign in the Deepwater Gunashli area was completed
safely and ahead of schedule, enabling subsea intervention on seven
wells that had previously been considered difficult to access using
conventional intervention methods.


Reportedly, the Central Azeri Gas Expansion (CAGE) project was
also successfully completed, increasing gas reinjection capacity on
the Central Azeri platform by 20% to help maximize recovery from
existing wells. The project involved upgrades to the platform's
four existing gas injection compressors with the work carried out
during live platform operations, without the need for a plant
outage or additional flaring.







The project also included modifications to compressor suction
manifold piping to support gas injection capacity increase and
enhance operational flexibility. These activities were carried out
during the Central Azeri platform’s planned maintenance programme
(turnaround - TAR) in August, followed by completion of all
post-modification activities.


BP Exploration (Caspian Sea) Limited is the operator on behalf
of the Contractor Parties to the ACG Production Sharing
Agreement.


ACG participating interests are: bp (operator - 30.37%), SOCAR
(35.30%), MOL (9.57%), INPEX (9.31%), ExxonMobil (6.79%), TPAO
(5.73%), ONGC Videsh (2.92%).
