Tune Sør is the third development phase for the Tune field. A single well, 30/8-A-21 H is to be drilled through a pre-existing satellite template. The plan does not entail penetration of hydrocarbon-bearing strata.

The activity is expected to last for approx. 20 days.

Drilling of the top hole sections is a preparation for connection of the satellite to Tune Main, which currently produces to the Oseberg Field Center.
