Türkmennebit (alternatively spelled Turkmennebit), also known by the translation of the name as Turkmenoil (in English) or Turkmenneft (in Russian; ), is the national oil company of Turkmenistan. It was established by a presidential decree reorganising parts of the former Ministry of Oil and Gas in July 1996, and has its headquarters in Ashgabat. The chairman of the company is Guychgeldi Baygeldiyev. The main oil fields operated by Türkmennebit are Goturdepe, Barsa-gelmez, Nebitdag, Körpeje, Gamyà Âlyja, ÃÂeleken and Kemer, mainly in Balkan Province near the Caspian Sea.
In May 2023 the Guardian published a report, blaming Turkmenistan in general and Turkmenoil in particular to be the worst in the world for methane emitting. The greenhouse gas was emitted in large amounts from flare stacks that had been extinguished and from a few pipeline leaks. Researchers suspected continuous flaring had been stopped to prevent conflicts with Turkmenistans laws and replaced by venting, which is also illegal, but much harder to detect. The data collected by Kayrros researchers indicate that two large fossil fuel fields leaked 2.6m and 1.8m tonnes of methane in 2022 alone, pumping the equivalent of 366m tonnes into the atmosphere, surpassing the annual emissions of the United Kingdom for 2022.
