Oil firm Neptune Energy made a small oil discovery near the Fenja field in the Norwegian Sea, Norway's Petroleum Directorate said on Wednesday.
The discovery is estimated to hold between 0.5 and 3.2 million cubic metres (mcm) 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 0.2-1.6 mcm of recoverable oil equivalents, down from 1-4 mcm seen previously.
Neptune's partners in license 586, where the exploration well was drilled, are DNO, Suncor Energy and Eni subsidiary Vaar Energy.
