BHP takes $2.8B writedown on Fayetteville/Haynesville shale assets acquired from CHK for $4.75B in 2011 (#msg-60162987)—but maintains 100% of the carrying value of shale assets acquired in the $12B buyout of HK in 2011 (#msg-65211152):

Why the different treatment of the two sets of assets? Because the assets acquired in the HK deal produce large amounts of shale oil and NG liquids, while the assets acquired from CHK produce almost exclusively NG.
