A Gazprom subsidiary is readying an evacuation plan for two polar bear cubs after they defied attempts to resettle them by returning to a temporary workers’ camp on the Kharasavey field.

The one-year-old cubs were spotted in the camp in the remote area of the Yamal Peninsula in northern Russia in December.

The field is a next development target for Gazprom in the area, with development drilling and infrastructure construction unfolding quickly.

The cubs soon got used to being fed by workers and refused to go back to the tundra despite barking from local dogs.

The regional gas producing subsidiary, Gazpromdobycha Nadym, decided to resolve matters by hiring a helicopter to transport the pair about 100 kilometres away from the settlement to the shore of the Kara Sea.

But the bears found their way back in about three weeks, although GPS trackers showed that they travelled a roundabout route of 600 kilometres on land and frozen sea, before arriving to a joyful reception from residents at the camp.

The workers have named the two bears Khara and Savey and even opened an Instagram blog to track their adventures.

A new plan calls for a longer journey for the cubs: Gazpromdobycha Nadym plans to fly them 300 kilometres to Gydansky nature reserve in the hope that their new residence will suit them. But the ability of Khara and Savey to outdo humans with their gadgets should not be underestimated.
