Oilfield firm Schlumberger ($SLB@US) is reporting an increase in third-quarter profits as the need for oilfield services increases. The company is pointing to a rebound in crude oil prices as a factor in the change with oil prices rising 64% since the beginning of the year, reaching $85 per barrel. While Schlumberger shares were down 1.11% in early trading, they are outgaining rivals like Baker Hughes ($BKR@US)—which fell 4.26%—and Halliburton ($HAL@US), which fell 4.20% early Friday.
