Resources per sea area

The North Sea contains about 44 per cent of the remaining resources. A distribution of the rest of the resources shows that 37 per cent remain in the Barents Sea and 19 per cent remain in the Norwegian Sea. A large percentage of the expected remaining resources in the Barents Sea have not yet been proven.

The North Sea is the engine in the Norwegian petroleum activities with 63 producing fields at year-end. Three fields, Brynhild, Gaupe and Oselvar, were shut down in 2018.

The Norwegian Sea has 18 producing fields. One new field, Aasta Hansteen, came on stream in December 2018. There are two producing fields in the Barents Sea.

Remaining petroleum resources per sea area as of 31 December 2018 – In million standard cubic metres oe

North Sea

The resource accounts for the North Sea show that 161 million Sm3 o.e. were sold and delivered from this part of the Norwegian Shelf over the last year. Gross reserves increased by 175 million Sm3 o.e, before production is deducted. This means that the remaining reserves in the North Sea have increased by 14 million Sm3 o.e. in 2018.

The increase in gross reserves can be attributed to the submission of the PDO for Johan Sverdrup construction phase two and the Nova field. There was also an increase in the reserves in several fields, such as Gudrun, Fram and Edvard Grieg.

Contingent resources in fields were reduced by 125 million Sm3 o.e. in 2018, in part due to the submission of a PDO for development of Johan Sverdrup construction phase two, and because resources were matured to reserves. Contingent resources in discoveries have increased by 46 million Sm3 o.e. compared with last year’s accounts, due in part to growth from new discoveries as well as the fact that the 35/12-2 (Grosbeak) and 24/6-1 (Peik) discoveries are now being assessed for development. Six discoveries were made in the North Sea in 2018. Resource growth is approximately 12 million Sm3 o.e.

The estimate for unproven resources is 715 million Sm3 o.e., a reduction of 10 million Sm3 o.e. compared with last year’s accounts.

Oil and condensate are quoted in million standard cubic metres (Sm3). NGL is quoted in million tonnes, and gas is quoted in billion standard cubic metres. The conversion factor for NGL in tonnes to Sm3 is 1.9. Total oil equivalents are stated in million Sm3 o.e., 1000 Sm3 gas = 1 Sm3 o.e.

Norwegian Sea

The resource accounts for the Norwegian Sea show that 57 million Sm3 o.e. were sold and delivered from this part of the Norwegian Shelf over the last year. At the same time, gross reserves were reduced by 21 million Sm3 o.e. before production is deducted. This entails a reduction in the remaining reserves in the Norwegian Sea amounting to 78 million Sm3 o.e. in 2018.

The reduction in gross reserves is mainly due to the fact that the reserves on the Maria field have been reduced to take account of lack of pressure support from water injection in the reservoir.

Contingent resources in fields were reduced by 10 million Sm3 o.e. in 2018. The reasons for this include the fact that resources have been matured to reserves, and that certain projects have been excluded since they are now assessed as not being commercial. The estimate for contingent resources in discoveries was increased by 21 million Sm3 o.e. compared with last year’s accounts. The most important reasons for this are the 6604/5-1 (Balderbrå) and 6506/11-10 (Hades/Iris) discoveries made in 2018.

Three new discoveries were made in the Norwegian Sea in 2018. Total resource growth is approximately 45 million Sm3 o.e. The estimate for unproven resources is 695 million Sm3 o.e., a reduction of 45 million Sm3 o.e. compared with 2017.

Barents Sea

The resource accounts for the Barents Sea show that 12 million Sm3 o.e. were sold and produced from this part of the Norwegian Shelf over the last year. At the same time, gross reserves were reduced by 17 million Sm3 o.e before production is deducted. This yields a reduction in remaining reserves of 29 million Sm3 o.e. in 2018.

The reduction in gross reserves is due to the fact that the reserves in the Snøhvit field have been reduced due to updating of the geological models.

Contingent resources in fields have increased by 16 million Sm3 o.e. compared with 2017. The reason for this is that a PDO has been approved for the resources in Johan Castberg and the resources have been transferred from discovery to field. Estimated contingent resources in discoveries have been reduced by 7 million Sm3 o.e.

Three new discoveries were made in the Barents Sea in 2018. Resource growth amounts to approximately 3 million Sm3 o.e.

The unproven resources in the Barents Sea include volumes in the Barents Sea south, southeast and northeast. This year’s estimate for unproven resources is 2 530 million Sm3 o.e., a reduction of 5 million Sm3 o.e compared with 2017.
