Whiting Petroleum to take $800-$900 mln impairment charge in Q4

Dec 11 (Reuters) - Whiting Petroleum said on Monday it will record an impairment charge of $800 million to $900 million in the current quarter due to a partial write-down of some assets in the DJ Basin in Colorado.

The company said in a regulatory filing that the write-down of its assets at the Redtail field is not expected to result in any cash expenditures. (http://bit.ly/2iPe7b8)
