Ceiling Test [Abstract]
Ceiling Test	Note 7—Ceiling Test The Company uses the full cost method to account for its oil and gas operations. Accordingly, the costs to acquire, explore for and develop oil and gas properties are capitalized. Capitalized costs of oil and gas properties, net of accumulated DD&A and related deferred taxes, are limited to the estimated future net cash flows from estimated proved oil and gas reserves, including the effects of cash flow hedges in place, discounted at 10%, plus the lower of cost or fair value of unproved properties, as adjusted for related income tax effects (the full cost ceiling). If capitalized costs exceed the full cost ceiling, the excess is charged to ceiling test write-down of oil and gas properties in the quarter in which the excess occurs. At June 30, 2012 and March 31, 2012, the prices used in computing the estimated future net cash flows from the Company’s estimated proved reserves, including the effect of hedges in place at those dates, averaged $2.48 and $2.97 per Mcf of natural gas, $106.60 and $107.99 per barrel of oil and $7.93 and $8.74 per Mcfe of Ngl, respectively. As a result of lower natural gas prices and their negative impact on certain of the Company’s longer-lived estimated proved reserves and estimated future net cash flows, the Company recognized ceiling test write-downs of $53.5 million and $20.1 million during the three months ended June 30, 2012 and March 31, 2012, respectively. The Company’s cash flow hedges in place at June 30, 2012 decreased the ceiling test write-down by approximately $1.2 million. The Company’s cash flow hedges in place at March 31, 2012 increased the ceiling test write-down by approximately $1.2 million. At June 30, 2011 and March 31, 2011, the prices used in computing the estimated future net cash flows from the Company’s estimated proved reserves, including the effect of hedges in place at those dates, averaged $3.40 and $3.27 per Mcf of natural gas, $94.00 and $85.38 per barrel of oil and $7.81 and $7.32 per Mcfe of Ngl, respectively. As a result of lower natural gas prices and their negative impact on certain of the Company’s longer-lived estimated proved reserves and estimated future net cash flows, the Company recognized ceiling test write-downs of $13.0 million and $5.9 million during the three months ended June 30, 2011 and March 31, 2011, respectively. The Company’s cash flow hedges in place at June 30, 2011 and March 31, 2011 reduced the ceiling test write-downs by approximately $3.9 million and $1.6 million, respectively.

The Company uses the full cost method to account for its oil and gas operations. Accordingly, the costs to acquire, explore for and develop oil and gas properties are capitalized. Capitalized costs of oil and gas properties, net of accumulated DD&A and related deferred taxes, are limited to the estimated future net cash flows from estimated proved oil and gas reserves, including the effects of cash flow hedges in place, discounted at 10%, plus the lower of cost or fair value of unproved properties, as adjusted for related income tax effects (the full cost ceiling).
