A Production Sharing Agreement (PSA) for the Azeri, Chirag and Gunashli (ACG) field in Azerbaijan’s sector of the Caspian was signed in September 1994 for 30 years between Azerbaijan International Operating Company (AIOC) and the State Oil Company of the Azerbaijan Republic (SOCAR).
The ACG field is located 100 kms east of Baku in water depth ranging from 125~180 meters. It was discovered in the early 1980’s and the shallow part called shallow water Gunashli was developed by SOCAR through several platforms and production started in 1985.
BP currently estimates total recoverable reserves in ACG over the PSA period (1994~2024) at 5.4 billion barrels of oil, with around 1.4 billion barrels of oil produced at the end of 2009. STOOIP is estimated at 17.4 billion barrels of oil, making ACG one of the largest oil fields in the world.
Early oil production began in November 1997 from the upgraded Chirag-1 existing platform.
During the period February 2005~April 2008, four fixed new production platforms were installed offshore and started production, namely Central Azeri, West Azeri, East Azeri and Deepwater Gunashli. All four platforms have similar design with 48-slot well bay and an average topside weight of 21.000 net tons.
In addition, adjacent to both Deepwater Gunashli and Central Azeri production platforms, a compression and water injection platform was installed.
A sixth production platform, Chirag Oil Platform (COP) was sanctioned in March 2010. COP design has a similar design to other production platforms and first oil is planned late 2013.
Wells (Producers, Water Injectors, Gas Injectors) at ACG are being drilled from the five Production Platforms and three subsea templates in the Deepwater Gunashli (Water Injection only). Up to mid 2010, over 100 new wells have been drilled and on average around 20 wells are been drilled every year across ACG field, up to 3800m vertical depth.
The ACG Crude Oil production in 2010 is around 830.000 bopd is sent through 3x30” and 1x28” oil export pipeline to Sangachal Terminal located 55kms south of Baku and covering 540 hectars.
ACG is currently producing up to 1200 mmmscf/d of associated gas (nearly twice as much as Shah Deniz Phase 1). Around 75% is being re-injected at Central Azeri platform for pressure support. A gas pipeline 1x28” links ACG field to Sangachal to handle surplus associated produced gas.
In addition to gas injection, production mechanism also includes water injection of 800.000 bwpd.
ACG Crude Oil main export routes are:
-85% via the Baku-Tbilisi-Ceyan (BTC) 1700kms pipeline connecting the Caspian Sea with the Mediterranean Sea.
-10% via the Western Route Export Pipeline (WREP) connecting the Caspian Sea with the Black Sea
-5% via Railway connecting Caspian Sea to the Black Sea.
