Oil firm Neptune Energy made a small oil discovery near the Fenja Field in the Norwegian Sea, Norway’s Petroleum Directorate (NPD) said Oct. 28.

The discovery is estimated to hold between 0.5 and 3.2 million cubic meters (MMcm) of recoverable oil equivalents, NPD said in a statement.

The drilling, however, also led to a reduction in size of the nearby Arc discovery, which is now estimated to contain between 0.2 MMcm and 0.6 MMcm of recoverable oil equivalents, down from 1 MMcm to 4 MMcm seen previously.

Neptune’s partners in license 586, where the exploration well was drilled, are DNO, Suncor Energy and Eni subsidiary Vaar Energy.
