LONDON (MarketWatch) -- Oilfield services-and-equipment firm Schlumberger Ltd. SLB, -0.25% said third-quarter net income jumped to $1.73 billion, or $1.38 a share, versus $787 million, or 65 cents a share, in the same period last year. Excluding charges and credits, net income attributable to Schlumberger rose 11% to $875 million, or 70 cents a share, the company said. A Factset Research survey of analysts produced a consensus forecast of 70 cents. Schlumberger said third quarter revenue rose to $6.85 billion from $5.43 billion. "We expect the fourth quarter to show continued strong activity in North America on land, but we do not expect any rapid return to deepwater drilling in the U.S. Gulf of Mexico despite the lifting of the moratorium," the company said in a news release. Elsewhere, the impact of BP's damaged Macondo well in the Gulf of Mexico is being reabsorbed, the company said, which together with "the recent strength in oil prices gives us some optimism that the rate of recovery overseas will accelerate slightly."
