On 17 September 2008, a small gas leak was discovered and one gas-injection well broached to surface in the area of the Central Azeri platform at the Azeri oilfield, a part of the Azeri–Chirag–Guneshli (ACG) project, in the Azerbaijan sector of Caspian Sea.[131][132] The platform was shut down and the staff was evacuated.[131] As the West Azeri Platform was being powered by a cable from the Central Azeri Platform, it was also shut down.[133] Production at the West Azeri Platform resumed on 9 October 2008 and at the Central Azeri Platform in December 2008.[134][135] According to leaked US Embassy cables, BP had been "exceptionally circumspect in disseminating information" and showed that BP thought the cause for the blowout was a bad cement job.
