Delineation of the 7324/8-1 Wisting oil discovery

25. september 2017

Successful data collection in the north.

Idemitsu Petroleum Norge is pleased to announce that drilling and testing of the Wisting appraisal well 7324/8-3 (Wisting Central III) has been successfully completed. The wellbore is located in production licence 537 in the southern Barents Sea and represents the sixth well in the license.

The Wisting Central III well was drilled by the semi-submersible drilling rig Island Innovator some two kilometres south of the discovery well 7324/8-1 and 315 kilometres north of Hammerfest.


The objectives of the well were to collect data to reduce uncertainties as regards the recoverable volumes, to perform a water injection test in reservoir rocks in the Stø Formation and to undertake a seismic monitoring study.


Well 7324/8-3 encountered an oil column of about 55 metres in Middle Jurassic to Upper Triassic sandstones (Stø and Fruholmen formations). The Stø Formation exhibited very good reservoir properties, while the Fruholmen Formation was found to be of moderate to good reservoir quality. The resource estimate on the Wisting discovery will be updated based on evaluation of the new well data. The result will be important for future maturation of the Wisting area concerning a potential development.


Extensive data acquisition and sampling was carried out, and a successful water injection test was completed in the Stø Formation.


Appraisal well 7324/8-3 was drilled to a vertical depth of 775 metres below sea level and was terminated in the Upper Triassic Fruholmen Formation.


Water depth at the site is 396 metres.

Hiroshi Arikawa, Managing Director of Idemitsu Petroleum Norge comments:

“I am satisfied to see that this important data acquisition in the Wisting Central III well has been successfully completed. This will undoubtedly strengthen the decision basis for a possible future development in the Wisting/Hanssen area.”
