The disclosure, made late Wednesday in a securities filing under sanctions law requirements that went into effect in February, said non-U.S. subsidiaries of Schlumberger provided oilfield services to the National Iranian Oil Co. in the first half of the year as the company completed its wind-down of the operations during the second quarter.
Schlumberger earned $102 million in revenue during 2013 for the Iranian activity, resulting in a net loss of $69 million, it said in the filing.
The company, which is the world’s largest oil field services firm, reported quarterly revenue of $11.2 billion, up more than 8% from the same period in 2012.
