"Chesapeake Energy (CHK) claims average EUR’s for the Marcellus at 4.2
Bcf. Range Resources (RRC) has claimed average EUR’s as high as 5.7 Bcf
in investor presentations. According to the USGS, however, the average
EUR for the Marcellus turns out to be about 1.1 Bcf. This is obviously problematic on many levels not least of which is
the fact that these companies can borrow money based on EUR expectations
and claims. If they have overstated EUR’s, then monies may have been
borrowed on assets that either simply don’t exist or are not
commercially viable ... Based on production data filed with the Texas Railroad Commission about
94% of all wells in the Barnett are underperforming their type curves ... To put into perspective how ridiculous Chesapeake’s claims of 2.6 Bcf
is, consider the following: of the company’s 742 operated wells
completed on the Fayetteville, only 66 have produced more than one Bcf
and none have produced more than 1.7 Bcf. Chesapeake’s average
Fayetteville well has produced only 541 Mcf."
