Norwegian oil and gas firm Equinor (NYSE: EQNR) submitted on July 3 a 7.8 billion crown (US$954.46 million) plan to develop gas reserves in the western part of its Troll field, the largest gas field off Norway.

The Nordic country is Europe’s top gas supplier after Russia, with gas exports from its Troll field estimated to account for 8% of the European Union's total gas consumption.

Reserves of 2.2 billion barrels of oil equivalent will be produced by using subsea installations tied-in to the Troll A platform, which is about 25 km (15.53 miles) north-west of the reserves, in the third phase of development, Equinor said in a statement.

“It has a break-even [price] of less than $10 per barrel,” said Margareth Oevrum, head of Equinor’s technology, projects and drilling.

Equinor holds a 30.58% stake in the Troll field, Petoro 56%, Shell (NYSE: RDS.A) 8.1%, Total (NYSE: TOT) 3.69% and ConocoPhillips (NYSE: COP) 1.62%.

Equinor said it would sign contracts on July 3 with marine installations and subsea facilities totaling 750 million crowns (US$92 million) with Allseas, Nexans and Deep Ocean.
