Improved recovery

According to current production plans, more than half of the proven oil resources in Norwegian fields will be left behind when production ends. One of the Norwegian Petroleum Directorate's primary tasks is to contribute to improved recovery from producing fields. Improving recovery by even just a few percentage points represents enormous values for the Norwegian society.

Positive prospects for producing more

A very significant potential for enhanced oil recovery (EOR) on the Norwegian continental shelf (NCS) has been identified by a recent technical screening study of various EOR technologies.

Large quantities of oil from gas injection

Since 1975, gas has been injected to increase recovery on the Norwegian shelf. The result is 320-360 million standard cubic metres more oil and condensate from the fields.

Improved recovery without side effects

New measures to increase recovery of oil from fields could lead to a more energy-efficient recovery, while emitting less chemicals and carbon dioxide than with current practices.

Long live chalk!

Research into the chalk reservoirs in the North Sea promises to extend the producing life not only of older Norwegian fields but also of discoveries in other parts of the world.

Why do we not recover 100 per cent of the oil?

To ensure a high recovery factor, good utilisation of the resources and value creation from the fields, access to appropriate technology, sufficiently qualified personnel and ability to take...

Well-filled toolbox for improved oil recovery

Ways of improving recovery from Norwegian fields are many and varied – just like the reservoirs involved. These methods include water, gas, water combined with gas, foam plus water and gas,...
