Equinor has completed an appraisal well (7324/7-4) on the Wisting discovery in the Barents Sea. The objective was to acquire data on the reservoir and cap rock, for use in ongoing evaluation and development of the discovery.

The well was drilled using the "Deepsea Stavanger" exploration rig, 300 kilometres north of Hammerfest. The well is located in production licence 537.

Geological information

The Wisting discovery was proven in Middle Jurassic and Upper Triassic reservoir rocks in the Realgrunnen Subgroup in 2013. The discovery is being evaluated for development along with the Hanssen discovery in the same production licence.

Well 7324/7-4 encountered the reservoir in the Stø and Nordmela formations with a total of 39 metres, with good reservoir quality. Extensive data acquisition and sampling have been carried out. The licensees will conduct extensive analyses of the collected samples and data in order to determine their significance for the Wisting development.

Appraisal well 7324/7-4 was drilled to a vertical depth of 870 metres below sea level and was terminated in the Fruholmen Formation in the Upper Triassic.

The water depth is 396 metres, and the well has been permanently plugged and abandoned.
