The company said in a news release that its workforce, which started the year at 95,000, ended the first quarter on March 31 with 93,000 employees. It had 126,000 employees in mid-2014, when oil prices started to drop.
A Schlumberger spokesman said Friday that the company cut about 8,000 employees but converted about 5,500 contractors to employees in the first quarter. That would suggest a workforce of 92,500 at quarter's end. The spokesman, who communicated by email, did not explain the discrepancy.
On Thursday, Schlumberger announced that first-quarter net income fell to $501 million, or 40 cents per share, from $975 million, or 76 cents per share, a year earlier.
Revenue fell 36 percent to $6.52 billion from $10.25 billion. Revenue in North America plunged by 55 percent and international revenue dropped 28 percent from a year ago.
The company, with bases in Paris, Houston, London and The Hague, Netherlands, is the world's largest oilfield-services provider, helping energy companies explore for and produce oil and gas. The business has sagged with the plunge in oil prices that started in mid-2014.
Chairman and CEO Paal Kibsgaard said Schlumberger is dealing with a decline in activity, pressure to cut prices, and job cancelations. The decline in drilling activity "reached unprecedented levels as the industry displayed clear signs of operating in a full-scale cash crisis," he said in a statement issued by the company after U.S. markets closed on Thursday.
In afternoon trading on Friday, the shares were down 51 cents to $79.76. They began the day up 15 percent in 2016 but were still down 32 percent from their peak in July 2014.
