The Galkynysh Gas Field, formerly known as Iolotan gas field or South Yolotan – Osman field, is a large natural gas field near Ýolöten in Mary Province of Turkmenistan. It is the world's second-largest gas field.[1]
The discovery of the gas field was announced on 2 November 2006.[2] Late Turkmen president Saparmurat Niyazov invited Chinese CNPC and Turkish Çalik Enerji to participate in the exploration and development of the Ýolöten field.[3] In 2008, the gas field was audited by Gaffney, Cline & Associates. According to Gaffney, Cline and Associates (GCA), Galkynysh is five times larger than the Dauletabad gas field and fourth- or fifth-largest gas field in the world.[4]
In December 2009, the contracts to develop the field were awarded to CNPC, Hyundai Engineering and Petrofac.
In November 2011, the field was renamed as Galkynysh.[5] Production started in September 2013.[6]
The gas field ranks among the world's five largest with estimated reserves of between 4and of natural gas and proven commercial reserves of .[7] [8] [9] It lies on 2700km2 zone of 90km (60miles) in length and 30km (20miles) in width in the depth of 3900to. Galkynysh consist of Iolotan, Minara, Osman and Yashlar fields.[5] Other nearby gas areas are Gunorta Garakel, Garakel, Giurgiu, Gazanly, Gundogar Eloten and Gunbatar Yandakly.[10]
Oil reserves are 300 million tons. The crude oil extracted at Galkynysh is transported to the Seýdi Oil Refinery.
