حقل دولت أباد للغاز الطبيعي
حقل دولت أباد للغاز ( Dauletabad Gas Field وأيضاً دولت آبات، دولتآباد دونمز، وحتى 1991 كان يُعرف بإسم سوڤيتآباد) هو حقل غاز طبيعي كبير يقع في مرو، ولاية مرو، تركمانستان. ويقع بالقرب من الحدود الإيرانية-التركمانستانية، ومسمى على اسم مستوطنة دولت أباد عبر الحدود في إيران.[1] الحقل هو جزء من جيحون، إقليم النفط والغاز.[1]

التاريخ
The Dauletabad structural feature was detected during geological surveys in 1957–1960. The Dauletabad arch was confirmed by seismic surveys in 1968. The exploratory wells confirming existence of natural gas reserves were drilled in 1972–1974.[1] Production started at the Dauletabad field in 1982.[2][3]
After the independence of Turkmenistan, production declined significantly, but increased again after 1998. The gas is exported via the Central Asia-Center gas pipeline system. Starting from December 2009, gas is supplied also to Iran through the Dauletabad–Salyp Yar pipeline.[4]
الاحتياطيات
Before production started in 1982, recoverable reserves of natural gas were estimated about 60 trillion cubic feet (1.7×1012 m3).[2] In 1992, its estimated recoverable reserves were 48.7 trillion cubic feet (1.38×1012 m3) of natural gas.[1] In 1997, the United States independent consultancy DeGolyer and McNaughton certified recoverable reserves at about 25 trillion cubic feet (710×109 m3).[2] In 2005, the Asian Development Bank estimated gross reserves 49.5 trillion cubic feet (1.40×1012 m3).[5]
It was considered to be the largest gas field in Turkmenistan until thorough evaluation of reserves at a newly discovered Yolotan field were made public.[6]
The Dauletabad field has been cited as a possible supply source for the Trans-Afghanistan Pipeline, but according to the Asian Development Bank, the field's production forecasts are "lower than expected" and that "production is predicted to decline."[5]
