Norwegian oil major Statoil plans to develop its Arctic Johan Castberg oilfield after having cut costs by half, with a decision on investments in 2017, its chief executive said on Tuesday.
Worried by high costs of operating in the remote Arctic Barents Sea, the Norwegian oil major last year delayed a final investment decision for Castberg, one of the world's northernmost oil finds.
"The investment estimate is almost halved from around 100 billion crowns ($11.29 billion) to between 50 and 60 billion crowns," Chief Executive Eldar Saetre told an industry conference on Tuesday.
He said costs for the field, expected to contain up to 650 million barrels of oil equivalents, could fall further.
"We still have possibilities to improve the project and I think we will make it work, now that we have decided to focus on one solution," Saetre told Reuters after
He declined to comment on what oil price the company needed for the project to break even.
Statoil said in November that the breakeven price was "well under" $60 per barrel. Independent Norwegian consultancy Rystad Energy said the breakeven price for Castberg is around $56 per barrel.
Since mid-2014, oil companies have postponed investments and laid off thousands of workers to cut costs in response to a tumble in the price of crude. Brent crude traded around $29 per barrel on Tuesday.
The firm and its partners have picked a floating production storage and offloading (FPSO) concept for the field, he added. Possible production start would be 2022.

's ENI are partners in the field.
Norway said in December it had given up seeking permission from European competition authorities to provide state support to bring oil and gas onshore from the Johan Castberg find.
So far Norway's only Arctic offshore field in production is Statoil's Snoehvit gas field in the Barents Sea.
ENI said on Tuesday it expects to start oil production at the Goliat field, the first oilfield in the Barents Sea, in three to five weeks pending completion of formal procedures.
That will make Goliat the world's most northerly producing offshore oilfield, the company said. The field was originally scheduled to start in November 2013, but has been delayed several times.
