News Summary: Halliburton 3Q earnings fall

SLOWING DOWN: Halliburton Co.'s earnings fell 12 percent in the third quarter as business fell off in its core North America market. Revenue growth of 9 percent was the smallest in more than two years.

PASS ON GAS: Some of Halliburton's customers are pulling back on drilling for natural gas because supplies are plenty and prices are down from a year ago. An increase in oil drilling hasn't made up for that.

HOLD ON TIGHT: Dave Lesar, Halliburton's CEO, says conditions in North America over the next couple of quarters could be "pretty bumpy."
