the Central Asia–Center gas pipeline system in April 2009 for which Turkmenistan blamed Gazprom. Natural gas exports include pipeline gas directly to China and Russia, and to Azerbaijan via a swap with Iran, plus liquid petroleum gas shipped by rail and truck to Afghanistan. In February 2022, Turkmenistan was identified as an ultra-emitter of methane by the European Space Agency's satellite-based TROPOspheric Monitoring Instrument, with the value of lost methane equalling about US$6 billion per year. Natural gas to gasoline production On June 28, 2019, a US$1.7 billion factory for producing gasoline out of natural gas was commissioned in Ovadandepe. Built by Rönesans and Kawasaki using technology from Haldor Topsoe, the factory has a design capacity of 600,000 tonnes of gasoline, 12,000 tonnes of diesel fuel, and 115,000 tonnes of liquefied petroleum gas per year, produced from 1.7 billion cubic meters of natural gas. According to opposition media, as of January 2023 the plant had halted production of export-grade ECO-93 gasoline due to a lack of catalyzers, and was producing only lower-quality gasoline for domestic consumption. Oil See also Turkmenistan / Oil Turkmenistan's major oil-producing area is in the west, mainly in Balkan Province, and is part of the South Caspian Basin, an intercontinental depression noted for oil production. Commercial oil production on the Turkmen side of the Caspian Sea began in the early 1900s, in the environs of the Cheleken Peninsula, and modern oil drilling began in the 1930s near Balkanabat. The Gumdag field was developed in 1949, then Goturdepe (1958), Ekerem (1962), and others. Offshore drilling began in the 1970s. Major onshore oil fields include Çeleken, Goñurdepe, Nebitdag, Gumdag, Barsagelmez, Guýujyk. Gyzylgum, Ördekli, Gögerendag, Gamyşlyja, Ekerem, Çekişler, Keýmir, Ekizek, and Bugdaýly. In 2019, capital investment in the oil industry totalled 3.29 billion manats. In January–November 2020, Turkmenistan extracted 8.7 million tonnes of oil and condensate. Production of liquid petroleum gas totalled 231,000 tonnes. The oil production and consumption data in the table below are taken from BP Statistical Review. Petroleum refining Oil is processed at two refineries, the Türkmenbaşy and Seydi oil refining complexes. The Turkmenbashy oil refinery had a refining capacity of more than 10 million tons of oil per year as of May 2016. The refinery produces a range of products, including unleaded gasoline, petroleum coke, asphalt, laundry detergent, hydro-treated Diesel, and lubricating oil. The Turkmenbashy oil refinery is Turkmenistan's largest producer of liquid petroleum gas,
