Schlumberger is buying Cameron in a cash-and-stock deal valued at about $12.71 billion that would create an oilfield equipment and service powerhouse. Cameron International Corp. shareholders will receive 0.716 shares of Schlumberger common stock and a cash payment of $14.44 for each of their shares. That equates to a value of $66.36 per Cameron share. That's a 56 percent premium to the Houston company's Tuesday, Aug. 25, 2015 closing price of $42.47.(AP Photo/Pat Sullivan, File)
