The Norwegian Petroleum Directorate shall contribute to creating the highest possible values for society from oil and gas activities, founded on a sound management of resources, safety and environment.

On average, the reserves in fields that are in production on the Norwegian shelf increased by 50 per cent compared with the volume estimated in the original, approved plan for development and operation (PDO). There has been a growth in reserves on both large and small fields. However, fields with a PDO dating from before 1991 have shown the largest increase in reserves. The estimate of oil volumes expected to be produced by these fields is almost 1 billion Sm3 higher today than that from 1990.
