Statoil发现天然气/凝析油资源

The well was drilled 8 km southeast of the 30/11-8 S (Krafla) discovery and about 27 km south of the Oseberg South facility in the North Sea.

The primary exploration target for the well was to prove petroleum in Middle Jurassic reservoir rocks (the Tarbert formation). The secondary exploration target was to prove petroleum in Middle Jurassic reservoir rocks (the Ness formation).

The well encountered gas columns at two levels in the top part of the Tarbert formation, a total of 5 m and 31 m, respectively, of which 4 m and 22 m had good to moderate reservoir properties. The secondary exploration target in the Ness formation is aquiferous.

The preliminary estimation of the size of the discovery is between one and three million standard cubic meters of recoverable oil equivalents. The discovery will be included in the evaluation of a new field development along with previous discoveries in the area.

Well 30/11-13 was drilled to a vertical depth of 3,313 m below the sea surface and was terminated in the Ness formation. Water depth at the site is 106 m.
