Shares and bonds in Norwegian Energy Company (Noreco) have been suspended after a request by the company.
Company stocks had plunged to a near record low last month after writedowns on two of its oil fields exceeded earlier estimates.
The company faced a number of financial difficulties following the shutdown of the Huntington field which resulted in impairments of about 700million kroner and 100million kroner.
A spokesman said: “Pending discussions concerning amendments to the summons, Norwegian Energy Company ASA has requested Oslo Børs for a temporary suspension of the company’s shares and bonds on Friday 12 December 2014.”
