Apache Corp I think I might have a good reason why Apache made their decision, just look at their share price drop from $120 to $80 over past 18 months and very low natural gas prices in North America - they probably want to conserve cash and focus on their core areas.
August 2011 Apache was trading over $120 then US debt ceiling crisis sent the stock down to $75. It got back to $110 in February 2012 but starting sliding when Natural gas fell out of bed last year. Natural gas is starting to fall out of bed again this year due to warm winter and storage almost full so not likely the stock will move much until North American gas prices start firming up - they pay a small dividend and probably not going to cut that during low natural gas prices so they decide on cutting expenses from non core areas?
