Halliburton Co.'s net income was flat in the second quarter as a slowdown in North American drilling offset an increase internationally. The Houston oil and natural gas services firm on Monday reported net income of $737 million, or 79 cents per share, from April to June. That compared with $739 million, or 80 cents per share, for the same period of 2011. Revenue increased 22 percent to $7.23 billion. (AP Photo/David Zalubowski, File)
