OSLO -- StatoilHydro Petroleum has hit oil in its secondary objective with wildcat well 30/8-4 S. The well is located west of Bergen and south of the Tune facility in the Oseberg area.
The primary exploration target for the well was to prove petroleum in Upper Jurassic reservoir rocks (intra Draupne formation in the Viking group). The secondary exploration target was to prove petroleum in Upper and Middle Jurassic reservoir rocks (upper Heather formation and upper Tarbert formation in the Viking and Brent groups, respectively).
No petroleum was proven in the primary target, but oil was proven in the secondary target in a section of the Tarbert formation. The size of the discovery is between 0.5 and 2.5 MMcm of recoverable oil, the company says.
A successful formation test was conducted.
The well is the fifth wildcat well in production license 190. The semisubmersibleTransocean Winner drilled the well to a vertical depth of 4,155 m (13,631 ft) below the sea surface, and the well was concluded in the Ness formation from the Middle Jurassic Age.
