Located in the UK Central North Sea, P.1946 comprises block 15/12a.
Stavanger owns a 20% option interest in the license.
The transaction has secured regulatory approvals from the Department of Energy & Climate Change (DECC) and the Secretary of State.
AziNor Catalyst executive director Henry Morris said: "We are very pleased to have captured this licence in this highly prospective region. Historically, poor quality 3D seismic over the block has meant that the visualising of the reservoir and its fluid fill has been difficult.
"However, recently acquired 3D seismic data has helped us to improve our understanding of the region’s prospectivity.
"This deal follows our strategy of advancing and unlocking the potential of UK plays and prospects through new data and technology.
The UK North Sea will continue to be a core area for AziNor Catalyst and we are actively targeting further licence acquisitions in this area."
