OSLO, June 20 (Reuters) - Norwegian oil firm Statoil and its partners are studying the possibilities ofexpanding gas production at Norway's biggest field, Troll, after2020, the company said on Monday.
The Troll field in the North Sea contains about 40 percentof Norway's gas resources and produced 34.6 billion cubic metresof gas in 2015.
"We are conducting a feasibility study on developing gasresources from the Troll West area... That would mean higher(gas) production post-2020," a company spokesman said, addingthat the study was at a preliminary stage.
The spokesman said the most likely scenario was to tie inthe Troll West area to the Troll A platform via a pipeline, withpotential investment estimated at a preliminary 10 billionNorwegian crowns ($1.21 billion).
He could not say by how much gas production at Troll couldbe increased.
State-owned Petoro has a 56-percent stake in the field, withmajority-state owned Statoil holding 30.6 percent.
The other partners are oil majors Shell with 8.1percent, Total with 3.7 percent and ConocoPhillips with 1.6 percent.
