Oil and Natural Gas [Member]

Reorganization Value, Methodology and Assumptions	Our oil and natural gas properties are accounted for under the full cost accounting method. The company determined the fair value of its oil and gas properties based on the anticipated cash flows associated with proved reserves and discounted using a weighted average cost of capital rate of 13.5%. The discount rate is commonly based on empirical studies of investment rates of return of publicly traded equity securities with investment return and risk characteristics similar to the subject company, which is consistent with a market-based approach. Weighted average commodity prices utilized in the determination of the fair value of oil and natural gas properties were $48.98 per barrel of oil, $2.68 per million cubic feet of natural gas and $18.51 per barrel of oil equivalent of natural gas liquids. Base pricing was derived from an average of forward strip prices. The company’s unproved acreage was determined to have no value due to capital constraints of our debt agreement and no plans to drill in our proved reserves cash flows. The company's salt water disposal assets were included in the cash flows of the proved reserves forecast, therefore, these values are included in the total value of our proved properties.
Drilling Equipment [Member]
Fresh-Start Adjustment [Line Items]
Reorganization Value, Methodology and Assumptions	The value of drilling rigs in operations (approximately $37.0 million) was estimated using an income-based approach utilizing discounted free cash flows over the remaining useful lives of the related assets. Anticipated cash flows associated with operating drilling rigs were discounted using a weighted average cost of capital rate of 13.8% for five years with a terminal value at the conclusion of the forecast period. The fair value of rigs not in operation, and other related drilling equipment (approximately $26.5 million), was valued utilizing a market-based approach with varying ranges of economic obsolescence rates to adjust for the impact of the oil and gas downturn.

Reorganization Value, Methodology and Assumptions	Gas gathering and processing equipment, transportation equipment and other was valued utilizing a market-based approach estimating what a market participant would pay for similar equipment in an orderly transaction. We utilized varying ranges of economic obsolescence rates depending on the underlying asset group. For pipelines and right-of-ways, we used a value per acre based on the location of the asset and estimated an average value of $129 per rod. We then applied an economic obsolescence rate of approximately 64% to determine the ultimate fair value.
