Norwegian operator Statoil has spudded the Korpfjell prospect in the Barents Sea.
The drilling site is in the northern sector of the Barents Sea, 37 kilometres from the Russian boundary and 415 kilometres from the Norwegian mainland.
Water depth at the site is 253 metres, and work is expected to last for 30 days starting this month.
The well is being drilled by Songa Enabler – a semi-submersible mobile drilling facility.
A spokesman for Statoil confirmed that drilling operations started at the Korpfjell well on Monday.
