PRM system installed on the Snorre field

Seismic streamers were installed on the Snorre field this past summer. When the streamers are lying exposed on the seabed, before they are covered, they are extremely vulnerable to trawling activity and other outside influences.

Work to complete the covering operation will start up again in the summer of 2014, with expected completion in the winter of 2015. Trawling activity in the area should be avoided during this period. The area in question lies within 61°31´N - 61°26´N and 2°17´E - 2°4´E. The guard vessel Asper Victoria will be present.

PRM (Permanent reservoir monitoring) is a project where streamers are permanently laid on the seabed to provide better, more frequent seismic images of changes in the reservoir. The streamers are used to obtain more information about the reservoir, thus making it possible to recover more oil.

The Snorre field is operated by Statoil and is located in blocks 34/4 and 34/7 in the North Sea, northeast of Gullfaks and southwest of Knarr. The water depth in the area is about 300 metres.

Around 250 kilometres of streamers were laid on the seabed at the Snorre field last summer. So far, however, not all of the streamers have been buried or covered with rock so trawling can take place.
