Despite some wild swings throughout the week, the S&P 500 ended the week with half of a percentage point gain. If you were an investor in Whiting Petroleum (NYSE:WLL) or Kodiak Oil & Gas (UNKNOWN:KOG.DL), you were handsomely rewarded, as the two companies decided to join forces to become the biggest oil and gas producer in the Bakken. Since the announcement, shares in Whiting and Kodiak were up a hefty 6.65% and 5.59%, respectively.
