OSLO, Norway – Seismic monitors will be installed on the seafloor over the Snorre field in the Norwegian North Sea to provide permanent reservoir monitoring, according to the Norwegian Petroleum Directorate (NPD).

A similar dedicated system will be installed on Grane in the same region, with all work scheduled for completion in early winter 2015. Statoil operates both fields.

Permanent reservoir monitoring is designed to provide a more frequent and better-quality seismic picture of changes in the reservoir. NPD says the ocean-bottom cable will be used to acquire more knowledge about the reservoir, hopefully leading to more oil production.

TheHavila Phoenix vessel will lay the cable on the seabed before it is trenched or covered with rocks to make it trawlable. The Northern Wave will perform subsequent trenching. On Grane, the Olympic Zeus will lay and bury the cable.

Snorre is in blocks 34/4 and 34/7 in water depths of 300-350 m (984-1,148 ft). Grane is in block 25/11 in 130 m (426 ft) of water.
