Equinor has made an oil discovery in well 25/11-H-1 H at the Svalin field in the North Sea.
The licensees will consider whether the discovery is sufficiently profitable for production.
Preliminary calculations show between 0 and 0.1 million standard cubic metres of recoverable oil equivalent, which is the equivalent of between 0 and 0.6 million barrels.
The discovery was made in a development well with the Deepsea Aberdeen rig in production licence PL169.
Geological information
The Svalin field was proven in 1992 in sandstone from the Palaeocene to early Eocene in the Heimdal and Balder Formations, and has been in production since 2014. The field consists of two separate structures; Svalin C and Svalin M. Svalin C has been developed with a subsea template tied back to the Grane installation and Svalin M has been developed with a multi-branch well drilled from Grane.
Development well 25/11-H-1 H encountered oil in thin sandstone layers (< 3 m) with very good reservoir quality in the Balder Formation, which is part of the Rogaland Group. The oil in the Balder Formation is presumed to be in pressure communication with surrounding reservoir sands in the Heimdal Formation on the Svalin C structure. The oil/water contact was not encountered.
