Equinor to link oil discovery to Visund field systems

Together with partners Petoro, ConocoPhillips, and Repsol Equinor is considering linking a recent oil discovery made with the Telesto exploration well in the Tampen area in the northern North Sea to existing infrastructure in Visund field. Resources are estimated at 12-28 million bbl of recoverable oil.

Geological data have been acquired for further analysis, and the well, which was not formation-tested, has been plugged. The licensees will consider linking the discovery to existing infrastructure on the field.

Well 34/8-18 S, drilled from the Visund A in production licence 120 was spudded on the 9^th February about 2½ kilometres east of Visund A and 155 kilometres west of Floro.

Drilled to respective measured and vertical depths of 6,039 metres and 3,298 metres subsea, the well was terminated in the Lunde formation from the Late Triassic Age. The prospect lies in 335 metres of water.

The objective of the well was to prove petroleum in Early Jurassic reservoir rocks (the Statfjord group). It encountered an oil column of about 115 metres in the upper and lower part of the Statfjord group, with effective reservoirs of 17 metres and 20 metres, respectively, in sandstone mainly with moderate reservoir quality.

In the upper part of the Lunde formation in the Upper Triassic, about 15 metres of aquiferous sandstone with poor reservoir quality was encountered.

The oil-water contact was encountered in the lower Statfjord group at about 3,170 metres subsea.

This is the 26^th exploration well drilled in the licence.

The Visund A platform will now drill development wells on Visund field.
