SchlumbergerSema reported first quarter revenue of $793 million, a 2% decline over the previous quarter, but up 12% year-on-year. Pretax operating income was $15 million, a decrease of 55% sequentially, and an increase of $14 million year-on-year. Schlumberger said that revenue for volume products of $202 million decreased 22% sequentially, but improved 1% year-on-year. The year-on-year improvement was mainly due to a 7% growth in mobilecom cards principally in North America and Europe, offset by a decline in parking terminals due to the exceptional Euro currency retrofit program that extended into early 2002. The sequential decrease reflected the seasonal drop in mobilecom activity, following telecommunications operators’ traditional Christmas campaigns coupled with reduced activity in prepaid phone cards.
