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[1] and its deep water section is a part of the larger Azeri–Chirag–Gunashli (ACG) project.

[1] 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).

Because of steadily falling rate of production (9%), SOCAR hired Kværner to provide project management to rehabilitate Gunashli.

It produces 140 tons of oil and 23,000 cubic metres (810,000 cu ft) of natural gas per day.

[4] The deep water section of Gunashli (also called DWG) field has been included for development within the ACG project's Phase III.

While the incident was blamed on an engineer, widespread rumors claimed that faulty and outdated equipment caused the fire.

[8][9] The fire started, according to SOCAR, when a high-pressure underwater gas pipeline was damaged in a heavy storm.
