The well was drilled about 137 kilometres west-northwest of Kristiansund in the Norwegian Sea.

The objective of the well was to prove petroleum in reservoir rocks in the Lange Formation and the Lysing Formation in the Upper Cretaceous (Turonian and Coniacian Ages, respectively). The well encountered mainly siltstone with thin layers of sandstone and dolomite stringers in both formations.

Data acquisition has been carried out. Attempts to collect pressure data and sampling indicate that the formations have low permeability and are partly tight.

The well is dry.

This is the sixth exploration well in production licence 209, awarded in the 15th licensing round.

Well 6305/5-C-3 H was drilled to a vertical depth of 4320 metres below sea level and was terminated in the Shetland Group from the Turonian. Water depth at the site is 925 metres. The well has now been permanently plugged and abandoned.

Well 6305/5-C-3 H was drilled by the Transocean Barents drilling facility, which will now continue in the same location to drill production well 6305/5-C-3 AH.
