The PJSC Lukoil Oil Company (Russian in Cyrillic script: Лукойл [ˈɫukɔɪɫ], stylized as LUKOIL and ЛУКОЙЛ in Russian Cyrillic) is a Russian multinational energy corporation headquartered in Moscow, specializing in the business of extraction, production, transport, and sale of petroleum, natural gas, petroleum products, and electricity.
It was formed in 1991 when three state-run companies from western Siberia merged. The original companies were named after the towns in Khanty–Mansi Autonomous Okrug where each was based: Langepasneftegaz, Urayneftegaz, and Kogalymneftegaz. Its new name is the combination of the acronym LUK (initials of the oil-producing cities of Langepas, Uray, Kogalym) and the English word oil.
