Simon Ayat, the chief financial officer of Schlumberger Ltd. (SLB), said Friday that the company likely would make another headcount reduction in the coming months.

Schlumberger was expected to announce more job cuts, in addition to the 5,000 employees, or 6% of its work force, announced in January.
