The Norwegian Offshore Directorate (NOD) has put in focus a major undeveloped gas discovery in the Norwegian Sea that could offer significant value, but warned that time is running out to bring it into production.

The Gro discovery, located about 160 km from the Åsta Hansteen field and 350 km west of Sandnessjøen, is one of the largest undeveloped gas finds on the Norwegian continental shelf.

The Directorate said the field needs to be tied back to existing infrastructure at Åsta Hansteen field before facilities in the area are decommissioned.

In ten years, it could be too late," said Arne Jacobsen, Assistant Director for Technology and Subsurface at the Norwegian Offshore Directorate.

Earlier estimates suggested a wide range of recoverable volumes between
