OSLO, Oct 29 (Reuters) - Norway's Equinor EQNR.OL wrote off $2.93 billion from the value of its assets after cutting its long-term oil and gas price forecasts on Thursday, betting the pandemic and a shift away from fossil fuels will have a lasting impact on markets.
The biggest hit came from a $1.38 billion write-off in the United States, most of it from the company's loss-making onshore shale oil and gas business, pushing Equinor to a net loss of $2.12 billion in the third quarter.
The energy major's adjusted profit before interest and tax (EBIT) fell 70% year on year to $780 million, lagging the $1.03 billion predicted in a poll of 24 analysts compiled by Equinor.
"Our financial results are impacted by weak prices as regions across the world are still severely affected by the pandemic," outgoing Chief Executive Eldar Saetre said in a statement.
The company, which is majority owned by the state, raised its dividend to $0.11 per share from $0.09 per share, still well below the $0.27 paid for the fourth quarter of 2019.
Equinor remains committed to resuming the $5 billion share buyback programme that was postponed earlier this year once conditions allow, said finance chief Lars Christian Bacher.
The asset write-offs follow similar decisions by BP BP.L , Royal Dutch Shell RDSa.L and other oil companies that have wiped tens of billions of dollars off their book values this year. biggest writedowns stem from Equinor's assets in the Bakken shale field in the United States and the Mariner heavy oilfield off the coast of Britain, the company said on an analysts call without elaborating.
OIL PRICE OUTLOOK
Equinor said it expects the price of the Brent crude benchmark to average $64 a barrel for the 2021-2050 period, higher than the $55 predicted by BP in June and also above Shell's long-term price forecast of $60 from 2023.
Equinor's expectation for Brent was set to $65 a barrel for 2025, down from $78 previously.
It also lowered its gas price outlook, forecasting British gas prices at $6.50 per million British thermal units (mmBtu), or 50.26 pence per therm in 2030, down from $7.7 per mmBtu previously.
"Significant uncertainty remains around the future commodity price development, underlining the importance of increased competitiveness and financial resilience," said Saetre, who said in August that he would retire at the end of October. crude was trading down 4.6% at $37.30 a barrel on Thursday, pressured by renewed coronavirus lockdowns, while the British day-ahead gas price TRGBNBPD1 was down 0.8% at about 38 pence per therm ($4.90 mmbtu).

Equinor's shares were down 1.8% by 1218 GMT and have lost 32.5% this year, outperforming an average 47% drop in European oil and gas stocks. .SXEP
