From an e-newsletter I receive......

"And just last month, energy and Peak Oil expert Chris Nelder wrote:

... the decline rates of shale gas wells are steep. They vary widely from play to play, but the output of shale gas wells commonly falls by 50% to 60% or more in the first year of production. This is why I have called it a treadmill: you have to keep drilling furiously to maintain flat output.

In the U.S., the aggregate decline of natural gas production from both conventional and unconventional sources is now 32% per year, so 22 bcf/d of new production must be added every year to keep overall production flat, according to Canadian geologist David Hughes. That's close to the total output of U.S. shale gas, after nearly a decade of its development. It will require thousands more shale gas and tight oil wells to keep domestic gas production flat.

So, what do you think?

Could Berman, Powers, and Nelder be the voice of reason in an otherwise overly-exuberant shale gas folly? Or are they simply sounding a false alarm?

Certainly, I don't pretend to know the answer to this question, but I would love to hear your thoughts on this.

And if you have any of your own data that you'd like to share, please feel free to do so in the comments section below."
