Wintershall Dea with promising discovery

Some 97 MMbo may have been found in the Bergknapp prospect situated in between the Maria and Kristin fields in the Norwegian Sea.

The primary exploration target for the well was to prove petroleum in reservoir rocks from the Early and Middle Jurassic (the Ile Formation and the Tilje Formation). The secondary exploration target was to prove petroleum in reservoir rocks from the Middle Jurrasic Age (the Garn Formation), NPD says in a press release.

In the primary exploration target, well 6406/3-10 encountered hydrocarbon-bearing sandstone layers totalling about 35 metres in the Ile Formation, with poor reservoir quality. The well encountered a total oil column of 120 metres in the Tilje Formation, with sandstone layers totalling about 75 metres with poor to good reservoir quality. The oil/water contact was not encountered.

In the secondary exploration target, a total oil column of about 60 metres was encountered in the Garn Formation, with sandstone of poor to moderate reservoir quality. The oil/water contact was encountered at about 4095 metres below sea level.

Preliminary estimates place the size of the discovery at between 26 and 97 MM million barrels of recoverable oil equivalents.

The licensees, including DNO and Spirit Energy, will consider tying the discovery in to existing infrastructure in the area.
