Since its commissioning, the Azeri-Chirag-Gunashli (ACG) field block in Azerbaijan’s Caspian Sea sector has produced 613 million tons of oil and 239 billion cubic meters of natural gas, according to the Ministry of Energy, as cited by Day.Az. Of this, 61.3 billion cubic meters of gas have been delivered to the state.
From January to August 2025, ACG maintained an average daily oil production of 44,000 tons, with daily oil exports averaging 327,000 barrels. The ownership structure of ACG includes bp as the operator with a 30.37% stake, AzACG (SOCAR) with 31.65%, MOL with 9.57%, Inpex with 9.31%, ExxonMobil with 6.79%, TPAO with 5.73%, Itochu with 3.65%, and ONGC Videsh Ltd.

The ACG project began with the signing of a production-sharing agreement on September 20, 1994, known as the “Contract of the Century.” This agreement was revised and extended until 2050 on September 14, 2017. In 2019, a final investment decision was made for the Central East Azeri (ACE) project, which started production in 2024, yielding 1.4 million tons of oil and 228 million cubic meters of gas to date.
