Norway’s oil and gas investments, a cornerstone of the country’s economy, are set to fall more than previously predicted next year, due to a sharp decline in exploration spending, data from Statistics Norway (SSB) showed Nov. 24.

Oil and gas firms have slashed spending repeatedly in their struggle to cope with the 60 percent drop in oil prices since June last year.

The fresh oil survey was broadly in line with the central bank’s forecast, economists said.

Overall 2016 oil industry investments are now seen falling 11 percent on the year to 171 billion Norwegian crowns (US $19.77 billion), against 181.2 billion seen in August and 24.7 percent below the 2014 all-time high of 227.3 billion.

The 2016 exploration estimate dropped by 35 percent to 21.5 billion crowns from a previous estimate of 33.3 million crowns.

“Due to low oil prices and operators’ processes to cut rig costs, the number of active rigs on the Norwegian Shelf is expected to decrease in 2016. The decrease in the exploration estimate for 2016 should be viewed against this background,” SSB said.

Norwegian oil major Statoil said on Nov. 23 it expected less exploration next year.

This year’s overall investments were seen at 192.8 billion crowns in line with an August estimate of 193 billion.

Norges Bank currently estimates a drop in petroleum investment of 12.5 percent this year compared to last year and a further drop of 10 percent next year.

Earlier on Nov. 24 Norway's consumer confidence fell to its lowest level in 23 years in the fourth quarter as the drop in crude oil prices continued to hit western Europe’s top energy producer, financial lobby group FNO said.

Norway’s vast offshore sector generates a fifth of the country’s GDP. The preliminary figures, compiled from oil firms by Statistics Norway, are revised every quarter.
