Revenues fell 39% to $7.74bn, with chief executive Paal Kibsgaard warning that there was "no signs" of an oil price recovery on the horizon.
Oilfield services giant Schlumberger has cut 10,000 jobs in the last three months amid the plunge in oil prices.
News of the near-10% jobs cull came as the firm unveiled a net loss for the last three months of $1bn - its first quarterly loss in 12 years.
Schlumberger also announced a $10bn share buy-back programme.
This news pushed the US company's shares 4% higher in after-hours trading. The stock price fell almost 20% is 2015 as investor worried that customers were cancelling projects as the oil price tumbled.
The profit figures were better than many analysts had expected, helped by heavy cuts to offset the slump in oil price.
The latest jobs cuts added to the 20,000 redundancies the company had already announced earlier in 2015.
Mr Kibsgaard warned that there were "no signs of pricing recovery in the short to medium term."
