Norway’s oil and gas production declined sharply in September, with natural gas output falling 12.6% from August, according to preliminary figures released Tuesday by the Norwegian Offshore Directorate (NOD).
Total petroleum production averaged approximately 3.77 million barrels of oil equivalent per day (boepd), down 10.4% month-on-month and 4% below the directorate’s forecast.
The decline comes at a sensitive time for European energy markets, with the winter heating season approaching and Norway remaining the continent’s largest supplier of pipeline natural gas.
However, the September slowdown contrasts with a stronger underlying trend: Norwegian petroleum production during the first nine months of 2026 remained 2.9% above the corresponding period last year.
Gas Output Takes the Biggest Hit
Norwegian natural gas production averaged 298.4 million standard cubic meters per day in September, down from approximately 341.6 million cubic meters per day in August.
The decline of 43.2 million cubic meters per day was particularly significant because production also fell 6.7% below the directorate’s forecast of 319.9 million cubic meters per day.
Total gas sales reached approximately 9 billion cubic meters during September, compared with 10.6 billion cubic meters in August.
The weaker performance coincided with the final stages of Norway’s annual offshore maintenance season.
In late August, pipeline operator Gassco warned that planned maintenance could temporarily reduce Norway’s natural gas export capacity by approximately 20% during parts of the period leading up to the end of September.
According to Gassco transparency data reported by Reuters, the median aggregate capacity reduction across Norwegian gas fields and processing facilities was expected to reach approximately 71 million cubic meters per day, equivalent to roughly one-fifth of typical daily deliveries.
The maintenance program was designed to prepare Norway’s offshore production and gas transportation infrastructure for the European winter, when demand typically increases.
However, the Norwegian Offshore Directorate’s September figures do not establish precisely how much of the production decline was attributable to scheduled maintenance rather than other operational factors.
Additional supply constraints emerged at the Shell-operated Ormen Lange field, where an extended outage was expected to reduce gas deliveries by approximately 7.9 million cubic meters per day until February 1, 2027.
Despite these challenges, Norwegian gas production remained 5.1% higher than in September 2025, suggesting that the sharp monthly decline does not necessarily indicate a sustained deterioration in the country’s production capacity.
Oil Production Falls by 145,000 Barrels Per Day
Crude oil production also weakened considerably during September.
Norway produced an average of 1.73 million barrels per day (bpd), representing a decline of approximately 145,000 bpd, or 7.7%, compared with August.
Production was also 8.4% lower than in September 2025.
However, unlike natural gas, crude oil output remained marginally above the directorate’s monthly forecast, exceeding expectations by 0.7%.
Total liquids production, including crude oil, natural gas liquids and condensate, averaged approximately 1.90 million bpd, down 168,000 bpd from August.
The distinction between oil and gas is important.
While both commodities experienced significant monthly declines, natural gas accounted for the more pronounced deviation from official expectations.
Norway’s Production Remains Ahead of 2025
Despite September’s weaker performance, Norway’s overall petroleum production continues to exceed last year’s levels.
During the first nine months of 2026, cumulative production reached approximately 181.7 million standard cubic meters of oil equivalent, an increase of 5.1 million cubic meters, or 2.9%, compared with the same period in 2025.
Crude oil production also exceeded the directorate’s cumulative forecast by 4.1%.
The figures illustrate why individual monthly production declines should be viewed in a broader context.
Norwegian offshore production is influenced by scheduled maintenance, operational interruptions, reservoir performance and the timing of new production capacity.
September’s decline therefore does not, by itself, signal a structural downturn.
Instead, the stronger year-to-date performance indicates that Norway continues to maintain substantial production capacity despite the operational challenges associated with its mature offshore industry.
Europe’s Dependence on Norwegian Gas
Norway’s production performance carries implications far beyond the Norwegian Continental Shelf.
Since the sharp reduction in Russian pipeline gas deliveries following the invasion of Ukraine, Norway has become Europe’s most important pipeline gas supplier, accounting for roughly 30% of combined European Union and British gas demand.
That dependence makes the reliability of Norwegian offshore production and transportation infrastructure increasingly important.
The September decline demonstrates how planned maintenance and operational disruptions can temporarily restrict supplies from a country that has become central to European energy security.
However, there are also reasons to distinguish temporary production constraints from longer-term supply risks.
On October 1, Gassco confirmed that its major scheduled maintenance activities had been completed, leaving Norway’s gas transportation system well positioned to meet European demand during the winter heating season.
The completion of the maintenance program removes an important temporary constraint, although the extended outage at Ormen Lange illustrates how individual field disruptions can continue to affect supply even after planned maintenance has ended.
For European gas markets, this distinction matters.
Norway’s ability to deliver large volumes of natural gas depends not only on pipeline capacity but also on the availability and performance of the offshore fields feeding the transportation network.
The Bigger Challenge: Sustaining Production
While September’s production decline may prove temporary, Norway faces a more fundamental challenge over the coming years.
Much of the Norwegian Continental Shelf consists of mature producing fields, where natural reservoir decline must increasingly be offset through additional drilling, improved recovery and new developments.
Maintaining production therefore requires continued investment, even when existing infrastructure allows smaller discoveries to be developed at relatively competitive costs.
The challenge is particularly relevant for Europe, where Norwegian gas has become an essential component of regional energy security.
Temporary disruptions can tighten gas balances during periods of high demand, while declining production capacity over time could increase dependence on alternati
