New seismic tools will result in 30 million extra barrels of oil from Snorre and Grane when Statoil and its partners now start using permanent reservoir monitoring (PRM). The technology will ensure a better understanding of the reservoirs.

Snorre and Grane are two oil fields with large remaining reserves. Now approx. 700 kilometres of seismic cables will be placed in trenches on the seabed on these to fields.

This covers an area totalling approx. 240 square kilometres (190 on Snorre and 50 on Grane). Combined, this will be the world's largest seismic project of its kind.

It will provide more frequent and better seismic images of changes in the reservoirs, and more knowledge of the reservoir will give more oil. With the current oil prices, we estimate that we could recover additional oil at a value NOK 19 billion on these two fields.
