Halliburton ( HAL) said Monday that an increase in activity in North America and in the Eastern Hemisphere boosted its third-quarter net income by 19%. The energy-services giant earned $729 million, or 79 cents a share, in the latest quarter, up from $611 million, or 58 cents a share, during the same period a year earlier. Halliburton generated $3.9 billion in revenue, up 16% from the third quarter of 2006. Included in the most recent third-quarter results were a boost from a $133 million tax credit and charges of $21 million. Excluding the gain from the tax credit, Halliburton's adjusted profit matched the analyst consensus estimate of 64 cents that was projected by Thomson Financial. CEO Dave Lesar said during a conference call that a strong performance in the eastern half of the globe and record quarterly revenue in North America were mostly responsible for the quarter's growth. "Our deployment of capital into international markets has resulted in Eastern Hemisphere revenue growth of 29% and operating income growth of 40% as compared to the third quarter of 2006," Lesar said in a press statement. Halliburton's solid North American results also provided a contrast with figures released last week by Schlumberger ( SLB), which said its results in the same region were weaker than expected during its third quarter. The Schlumberger announcement had weighed heavily on the entire oil-services sector Friday.
