Statoil makes important gas discovery in the North Sea – Offshore.no

Statoil has made a gas / condensate discovery northeast of Ekofisk – just off King Lear discovery in the southern North Sea.

According to a Message from NPD are found on Julius prospect between 15 and 75 million barrels of recoverable oil equivalents.

Before spud, the resource estimate in King Lear 69-201 million barrels.

The definition of 2 / 4-21 discovery does not lead to change of resource estimates, reports NPD.

– King Lear – and Julius discoveries located in one of the most mature areas on the Norwegian shelf – only 20 kilometers north of Ekofisk, the first commercial discovery made on the Norwegian shelf 45 years ago. The findings confirm the group’s belief that even such mature areas on the Norwegian shelf still has an interesting exploration potential, says May-Liss Hauknes, senior vice president for exploration on the North Sea.

41 meter gas

The primary exploration target for the well was to prove petroleum in Upper Jurassic reservoir rocks (Ula formation) and Middle Jurassic reservoir rocks (the Bryne formation), as well as to refine 2 / 4-21 discovery (King Lear ).

In primary exploration target well encountered 41 meters of gas / condensate filled sandstone rocks in the Ula formation with moderate reservoir quality. oil-water contact was not encountered.

The well encountered further 30 meters gross of water filled sandstone with poor reservoir quality in the Bryne Formation.

The well encountered also a 20 meters thick gas / condensate column in Farsund Formation, two zones of five meters thick reservoir rocks with moderate / good reservoir quality, as confirmed pressure connection with found 2 / 4-21 King Lear.

Now findings considered

The licensees will evaluate the findings with regard to optimum development.

Low 2/4 -23 S was drilled to a vertical depth of 5548 meters below sea level and was concluded in sandstones in the Skagerrak formation in the Upper Triassic.

The water depth is 68 meters. The well will now be permanently plugged and abandoned.

Well 2 / 4-23 S was drilled by the Mærsk Gallant which is moving to license 018 to do well work on the Eldfisk field in the North Sea.
