On Monday, the U.S. Department of Energy announced it was cutting its estimate of recoverable natural gas reserves in the Marcellus shale by 66%. The Department now says that 141 trillion cubic feet of gas may be recovered from the shale, versus the 410 Tcf the agency had previously reported. This adjustment comes with the increased drilling activity, and subsequent reporting of oil and gas company well results.
One such company, Range Resources
Range increased its proved reserves to 5.1 Tcfe, a 14% increase over 2010. This is especially noteworthy considering the company's April sale of its Barnett shale assets. Asset divestitures in 2011 reduced proved reserves by 904 Bcfe. But no matter! Range replaced 850% of 2011 production, adding 1,493 Bcfe of proved reserves through the drill bit. The company did not add any reserves through acquisitions in 2011, and total production totaled 202 Bcfe.
Too much gas?
As the DOE announced its revised outlook on natural gas reserves, Chesapeake Energy
First, even though Chesapeake is the No. 2 producer of U.S. natural gas, cutting its production numbers alone won't have much of an effect on methane prices. Second, a closer look at Range's proved reserves reveals some important truths.
Right now, the ethane that Range produces in the Marcellus shale is sold in the natural gas stream and not as the lucrative natural gas liquid it actually is. In 2013, companies will begin taking ethane deliveries from Range and the gas will be sold separately. As such, ethane will be treated like an NGL, improving Range's liquids production ratio and its bottom line.
The chart below illustrates the difference ethane can make when sold separately.

Marketing ethane as an NGL nearly doubles Range's NGL production. This is something long-term investors should keep in mind.
The Department of Energy expects there is 482 Tcf of recoverable gas across all U.S. shale plays. In 2010, 23% of domestically produced gas came from a shale play, and that number will increase to 49% by 2035. Thus, while total estimates have been scaled back, there is still plenty of room for companies like Range Resources to grow.
Range's crude oil production increased by 1% as natural gas production actually decreased by 1% in 2011. This point, hedging on 75% of 2012 natural gas production volumes, and the company's plan to redirect spending to liquids-rich plays, helps relieve some of discouragement brought on by low natural gas prices.
