The well is being drilled using the Bredford Dolphin semi-submersible drilling rig to a planned depth of about 2,275m below mean sea level.

According to the company, the objective of the well is to appraise the Avaldsnes discovery following the 16/2-6 discovery well in 2010 and the recent successful appraisal well 16/3-4 with side-track 16/3-4A.
