PetroNeft said it had agreed to take out a $2m loan facility with Swedish company Petrogrand, maturing 31 December 2018.
The loan would be used for general corporate purposes and to finance a potential drilling programme in 2018.
Discussions with partners on a 2018 drilling programme were ongoing, the company said.
"This loan facility will provide time and space for a more long-term financing solution to be put in place," it added.
Winter production from Sibkrayevskoye, meanwhile, was getting underway now that winter roads had become available.
