OSLO, Oct 15 (Reuters) - Norway’s trade surplus rose last month to a record level thanks to soaring revenues from selling gas from its offshore fields, national statistics agency (SSB) data showed on Friday. With a daily output of around four million barrels of oil equivalent, almost equally divided between oil and natural gas, the Nordic country is among the winners here from an ongoing spike here in global energy prices. The trade surplus for September rose 28% from August to 53.7 billion Norwegian crowns ($6.37 billion), the highest on record, SSB said.
