Norway's September oil output was 7.7% lower than the Norwegian Petroleum Directorate's (NPD) forecast, and 4.1% below the forecast so far this year, NPD announced on Tuesday.
The directorate explained that the main reason that production in September was below forecast was to do with technical problems on some fields.
The Nordic country's daily production of oil, natural gas liquids and condensate was about 1.57 billion barrels for the month of September, according to the statement.
Furthermore, the country's total gas sales for September saw a monthly decrease of 2.4 billion cubic meters compared to August to reach 5.8 billion cubic meters.
