The well has been drilled about 105 kilometres southwest of the Aasta Hansteen field in the Norwegian Sea and 362 kilometres west of Sandnessjøen.

The objective of the well was to prove petroleum in Upper Cretaceous reservoir rocks (the Springar Formation).

Well 6604/6-1 encountered a total of about 185 metres of sandstone rocks in the Springar Formation, with reservoir rocks in three zones totalling about 120 metres. The reservoir rocks are mainly of poor to moderate reservoir quality. The sandstones contain traces of gas. The well is classified as dry.
Data has been collected and samples have been taken.

This is the second exploration well in production licence 894. Well 6604/6-1 was drilled to a vertical depth of 3606 metres below sea level and was terminated in the lower part of the Springar Formation in the Upper Cretaceous.

Water depth at the site is 1127 metres. The well will now be permanently plugged and abandoned.

Well 6604/6-1 was drilled by the Scarabeo 8 drilling facility which will now drill appraisal well 6604/5-2 S in production licence 894 in the Norwegian Sea, where Wintershall Dea Norge AS is the operator.
