Norwegian oil firm Det Norske said it will appeal a government decision to give it a smaller stake in the Johan Sverdrup oilfield than it had been seeking.
The company revealed their plans as it reported lower than expected second quarter earnings for 2015.
Det Norske believes it should have been given a larger share than the percentage proposed by operator Statoil of 11.89%.
Det Norske said it was consdiering a bond issue in a bid to strenghten its finances after reporting lower-than-expected profits in the first quarter.
The Norwegian company said a consortium of seven banks have underwritten a revolving credit facility worth $500million.
It is also considering a $300million bond issue.
