Wintershall

German multinational oil and gas producer Wintershall has discovered oil in the Hibonite exploration well (5504/1-3) in Licence 5/06, in the Danish territory of the North Sea.

Located about 337km north of Den Helder in the Netherlands and 278km west of Esbjerg in Denmark, the exploration area Hibonite is nearly seven kilometres north of the field Ravn, which was developed by the company in 2009 with the Ravn-3 well.

Member of the board of directors at Wintershall, Martin Bachmann, who is responsible for Exploration and Production, said: "The Hibonite discovery is an exciting and important step towards becoming a producer in the Danish North Sea."

As per preliminary resource estimation from the company, the Hibonite formation is expected to contain about 100 million barrels of potential crude oil in place.

In water depths of 52 metres, the bore Hibonite-1 was drilled to a total depth of 4,431 metres below sea level. Wintershall collected cores, performed several well logs and produced oil and gas during a production test in the drilling programme.

"The company drilled two deflected holes, Hibonite-1A and-1B, to further analyse the size of the oil discovery."

The company drilled two deflected holes, Hibonite-1A and-1B, to further analyse the size of the oil discovery, while both wedge holes have confirmed oil-bearing sandstone formations of the Upper Jurassic.

Wintershall holds a 35% stake and operatorship in Hibonite, while other partners include Bayerngas Petroleum AS Denmark, Nordsøfonden and EWE Sales, with 30%, 20% and 15% interests respectively.

The company currently operates three licenses – 4/06a, 4/06b and 5/06 – and holds 35%, 80% and 35% stakes in the licenses respectively.
