Share-Based Compensation [Abstract]

Schedule of calculated fair value of options granted and major assumptions used

QEP uses the Black-Scholes-Merton mathematical model to estimate the fair value of stock options for accounting purposes. Fair-value calculations rely upon subjective assumptions used in the mathematical model and may not be representative of future results. The Black-Scholes-Merton model is intended for measuring the value of options traded on an exchange. The calculated fair value of options granted and major assumptions used in the model at the date of grant are listed below:

	Stock Option Variables Six Months Ended June 30, 2012
Fair value of options at grant date	$	14.46
Risk-free interest rate		0.81	%
Expected price volatility		55.9	%
Expected dividend yield		0.26	%
Expected life in years		5.0

Restricted Shares and Performance Share Units Activity

Restricted share grants typically vest in equal installments over a three or four-year period from the grant date. The total fair value of restricted stock that vested during the six months ended June 30, 2012 and 2011 was $12.6 million and $9.9 million, respectively. The weighted average grant-date fair value of restricted stock was $30.74 per share and $39.14 per share for the six months ended June 30, 2012 and 2011, respectively. As of June 30, 2012, $25.3 million of unrecognized compensation cost related to restricted shares granted under the LTSIP is expected to be recognized over a weighted-average vesting period of 2.4 years. Transactions involving restricted shares under the terms of the LTSIP are summarized below:

	Restricted Shares Outstanding			Weighted-Average Price
				(per share)
Unvested balance at December 31, 2011		1,099,752		$	32.80

Performance Share Units

Cash payouts are dependent upon the Company's total shareholder return compared to a group of its peers over a three-year period. The awards are denominated in share units but delivered in cash at the end of the performance period. The weighted average grant-date fair value of the performance share units was $30.90 per share and $39.07 per share for the six months ended June 30, 2012 and 2011, respectively. As of June 30, 2012, $5.3 million of unrecognized compensation cost, or the fair market value, related to performance shares granted under the CIP is expected to be recognized over a weighted-average vesting period of 2.4 years.

Transactions involving performance share units under the terms of the CIP are summarized below:

	Performance Share Units Outstanding			Weighted-Average Price
Unvested balance at December 31, 2011		115,274		$	39.07
