NCS: Duster for Equinor near Johan Sverdrup

The second exploration well in PL502 encountered traces of oil in a zone of about 19 m, but Equinor can’t determine if it’s producible or residual.

The Klaff prospect was drilled just 1 km away from Johan Sverdrup field,  and Equinor’s objective was to investigate potential reservoir rocks in several levels: Upper Jurassic intra Draupne Fm sandstones, Upper Triassic Skagerrak Fm, Upper Permian Zechstein Gp and weathered/fractured basement rock.

The 16/5-7 well drilled about 110 m of basement rock, of which 77 m of weathered and fractured basement rock with poor to moderate reservoir properties. Traces of oil were encountered in the upper part of the basement.

The well provided important information about reservoir potential in the basement rock, as well as pressure communication in the area.

No sedimentary rocks were encountered in other levels.

Until further investigation of collected data, the well is preliminarily classified as dry.
