A pipeline at an oilfield operated by a subsidiary of Gazpromneft, the oil arm of Russian gas producer Gazprom, burst and caught fire early on Saturday, the energy ministry said.
The incident occurred at the Ety-Purovskoe oilfield in the Yamal-Nenets region of western Siberia.
No one was hurt and workers were in the process of shutting down the oil wells there, the ministry said.
