Schlumberger CEO Paal Kibsgaard commented: “Schlumberger third-quarter results reached new highs in both revenue and pretax operating income driven by consistent performance across all geographic Areas through strong execution based on integration, quality and efficiency. The international business grew further, with leading margins expanding in spite of some operational delays. Performance in North America was particularly strong despite continued pricing weakness in the land market. Operating margins exceeded 20% in all Areas and expanded in all Product Groups. Results were led by North America with a new high in overall revenue, supported by solid offshore activity and the seasonal rebound of activity in Western Canada. US land operations showed impressive resilience through improved efficiency, new technology penetration and market share gains in a highly competitive market with largely constant rig count. International results were led by the Middle East & Asia with growth in key markets in Saudi Arabia and Iraq, while offshore activity strengthened in Asia, and land drilling and stimulation activity improved in China. Europe/CIS/Africa saw strong summer activity in Russia and Central Asia and a seasonal increase in WesternGeco marine activity in the Area. Latin America activity was driven by Integrated Project Management and Schlumberger Production Management operations.
