According to Russia's Federal Customs Service, crude oil, oil products and natural gas accounted for 68% of Russia's total export revenues in 2013, at US$356bn. Crude oil exports accounted for 1/3 of total export revenues, at US$174bn, which broadly corresponds to combined oil products exports (US$109bn) and gas exports (US$73bn). Europe, including Turkey, receives most of Russia's exports of crude oil and products, as well as virtually all exports of natural gas (piped gas). Asia (especially China) receives substantial volumes of crude oil and some liquefied natural gas (LNG) from Russia. Domestic sales of crude oil, gas and oil products were much lower, at US$122bn: in the case of petroleum products, domestic sales amounted to US$102bn (compared to US$109bn for exports).
Oil and natural gas activities make up a large portion of Russia's federal budget. According to the Ministry of Finance, 50% of Russia's federal budget revenue in 2013 came from mineral extraction taxes and export customs duties on oil and natural gas.
