The company kicked off earnings from hard-hit U.S. oilfield service providers as new lockdowns in some parts of the world due to a resurgence in infections threaten a recovery in oil demand. Global oil prices traded at $42.56 a barrel on Friday, down 36% this year..

North American markets have fared much worse than international markets, with Schlumberger's revenue from the region falling to $1.16 billion, from $2.85 billion a year earlier.

Total revenue plunged 38% to $5.26 billion.

Shares were down 5% at $15.52 in early trading.

"International activity is steady following budget resets completed in the third quarter," Chief Executive Officer Olivier Le Peuch said in a statement. North American business was "set for continued momentum," pointing to more drilled-but-uncompleted well completions and a modest resumption in drilling activity, he said.

International activity will begin expanding in 2022, Le Peuch told investors on a call, suggesting revenue from Schlumberger's largest sector would be flat next year.

Last month, Schlumberger agreed to sell its North American shale fracking business to rival Liberty Oilfield Services as part of Le Peuch's restructuring to focus on higher-tech businesses. He has bet on asset sales, as well as expense and job reductions, to weather weaker demand.

The company anticipates $1.5 billion in cost-savings as a result of its restructuring. Some 80% of that benefit was realized by the third quarter, Le Peuch told investors.

The company recorded charges of $310 million in the third quarter, adding to the over $12 billion it took in the previous two quarters. Job severance costs were $273 million in the quarter and $699 million year to date.

Le Peuch also is driving for new technology partnerships and accelerating Schlumberger's New Energy business, which aims to drive more sustainable energy output. That push fits with customers shifting their businesses to capitalize on the energy transition.

Schlumberger reported a net loss of $82 million, or 6 cents per share, for the quarter ended Sept. 30. Excluding charges and credits, it earned 16 cents per share in the quarter, helped by cost cuts.

The company reported a net loss of $11.38 billion, or $8.22 per share, a year earlier, due to impairment charges.
