Schlumberger  (SLB) shares were down more than 0.5% premarket after the oilfield services company reported first quarter revenue below analyst expectations for the period. 

The company reported earnings of a quarter per share, matching Wall Street's expectations for the period, but revenue of $6.89 billion missed analysts' $6.98 billion forecasts. 

"In the first quarter, the North America land market continued to strengthen in terms of both activity and pricing, leading us to begin accelerating deployment of idle capacity for multiple product lines," CEO Paal Kibsgaard said.
