Germany-based crude oil and natural gas producer, Wintershall, has announced oil discovery during the drilling of Hibonite exploration well 5504/1-3 in 5/06 license, in the Danish sector of the North Sea.

The 5504/1-3 well located in the Hibonite structure is about 337km north of Den Helder, the Netherlands and 278km west of Esbjerg, Denmark and was drilled to a total depth of 4,431m vertically below sea level with water depth of 52m.

Logging program was carried out on the cores and during the production test oil and gas were produced.

Initial resource estimates of the well suggest a potential of about 100 million barrels of oil in place.

The Hibonite prospect situated nearly 7km north of the Ravn field is formed by Upper Jurassic Heno sandstones.

Wintershall Exploration and Production board member Martin Bachmann said that the Hibonite discovery is an exciting and important step towards becoming a producer in the Danish North Sea.

To further evaluate the extent of the oil discovery, Wintershall drilled two sidetrack wells, Hibonite-1A and Hibonite-1B, which confirmed the presence of oil bearing sandstone of Late Jurassic age.

Wintershall is the operator of Hibonite license and holds 35% interest, while other partners of the license are Bayerngas Petroleum Denmark, Nordsøfonden and EWE Vertrieb with 30%, 20% and 15% interest, respectively.
