Anadarko said Thursday it will increase capital spending to $5.6 to $6 billion in 2011 up from $5.2 billion in 2010 as it develops projects in Africa and the U.S. It plans to allocate 10% of its capital to developing the Eagleford and Marcellus shale plays in the U.S. The company expects to announce a joint-venture agreement in the Eagleford soon. Output is expected to increase to 244 million barrels of oil equivalent (mmboe) to 248 mmboe in 2011. It projects a 10% increase in liquid volumes that will deliver higher margins. The company's operations in Algeria have not been disrupted by protests in that country, but Anadarko has halted operations in the Ivory Coast. 16 analysts rate the stock a buy, 12 a hold.
