Equinor to link oil discovery to Visund field systems

March 4, 2019
Equinor together with partners Petoro, ConocoPhillips, and Repsol will consider 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.

Equinor together with partners Petoro, ConocoPhillips, and Repsol will consider 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 (OGJ Online Sept. 5, 2018).

Well 34/8-18 S, drilled from the Visund A in production license 120 was spudded Feb. 9 about 2½ km east of Visund A and 155 km west of Floro. Drilled to respective measured and vertical depths of 6,039 m and 3,298 m subsea, the well was terminated in the Lunde formation from the Late Triassic Age. The prospect lies in 335 m 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 m in the upper and lower part of the Statfjord group, with effective reservoirs of 17 m and 20 m, respectively, in sandstone mainly with moderate reservoir quality.

In the upper part of the Lunde formation in the Upper Triassic, about 15 m of aquiferous sandstone with poor reservoir quality was encountered. The oil-water contact was encountered in the lower Statfjord group at about 3,170 m subsea.

This is the 26th exploration well drilled in the license. The Visund A platform will now drill development wells on Visund field.
