Estimates used in the determination of carrying amounts of assets or liabilities, or in disclosure of gain or loss contingencies should be disclosed if known information available prior to issuance of the financial statements indicates that both of these criteria are met: (1) It is at least reasonably possible that the estimate of the effect on the financial statements of a condition, situation, or set of circumstances that existed at the date of the financial statements will change in the near term (less than one year from the date of issuance) due to one or more future confirming events, and (2) The effect of the change would be material to the financial statements.No definition available.false0USE OF ESTIMATESfalseUSE OF ESTIMATESUnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.crimsonexploration.com/role/DisclosureUseOfEstimates12
