According to partner Atlantic, the semisubmersible West Hercules is re-entering well 6104/21-2 Brugdan II in 460 m (1,509 ft) of water in Faroese license 006.
Brugdan is a large four-way dip closure at Tertiary level that was drilled in 2006 by the 6104/21-1 well. This was abandoned prior to reaching the Vaila sandstone target owing to mechanical issues.
The current well is expected to take more than two months to complete.
Atlantic CEO Ben Araboa said: “Although the well is both geologically and technically challenging, it could, if successful, have a very big impact on Atlantic Petroleum and on the Faroese shelf in general.”
Other partners are ExxonMobil and OMV.
