Gunashli (Azerbaijani: Günəşli) is an offshore oil field in the Caspian Sea, located 120 kilometres (75 mi) east of Baku, Azerbaijan, 12 kilometres (7.5 mi) southeast of Oil Rocks and its deep water section is a part of the larger Azeri–Chirag–Guneshli (ACG) project. The Azeri translation of Gunashli means "sunny". Gunashli is believed to have more than 100 million tonnes of oil reserves.
The portion of Gunashli field which is not in the scope of ACG project, lies in 120 metres (390 ft) depth of water and developed by State Oil Company of Azerbaijan Republic (SOCAR) while the deepwater section developed by BP within ACG project is at 175 to 300 metres (574 to 984 ft).
The field was explored in 1958–63. The first offshore platform was installed by 1976. Production in this section started in 1982. It consisted of 4 steel jackets for drilling of 10 wells. As per 1980 data, the platform produced 320 tonnes of oil per day.
As of 1995, Gunashli was producing 120,000 barrels per day (19,000 m3/d) of oil. Because of steadily falling rate of production (9%), SOCAR hired Kvaerner to provide project management to rehabilitate Gunashli. In March 2008, a high-flow-rate well No. 244 was put into operation through the platform No. 13. It produces 140 tons of oil and 23,000 cubic metres (810,000 cu ft) of natural gas per day. The well was drilled by SOCAR subsidiary Azeri Drilling Company Ltd. The well No. 247 was drilled by Bayil Limani Offshore Exploration Drilling Unit through platform No. 14. It produces 100 tonnes per day.
The deep water section of Gunashli (also called DWG) field has been included for development within the ACG project's Phase III. First oil from DWG was produced on 20 April 2008 from one of 10 pre-drilled wells. DWG now produces nearly 320,000 barrels per day (51,000 m3/d) of the total 1 million barrels per day (160×103 m3/d) from ACG fields complex. ACG's DWG complex is located in the eastern side of the Gunashli field and includes two bridge-linked platforms:
