●Aggregated detailed well production data (HPDI) for nearly 100% of total U.S. natural gas volumes reveals that almost 2/3s of total current natural gas production is from wells drilled just in the past five years or since a host of shale plays really began to alter the U.S. natural gas landscape.
●Meanwhile, we would note that the overall U.S. natural gas production decline rate (Ex. Appalachia) accelerated in 2012 and averaged ~26% due to a higher ratio of new wells that came on line in 2011 and which posted high first-year decline rates of ~50%. With fewer new wells brought on line last year, we expect decline rates to moderate to ~24 % in 2013 and ~23% in 2014 due to a lower proportion of new wells in the U.S. natural gas production mix.
●Nevertheless, the ~23-24% decline rates imply that domestic natural gas production would need to grow by ~17 Bcf/day annually just to offset natural declines and keep current production flat.

westexas wrote:In any case, no problemo. Based on above estimates (24%/year decline rate for existing gas, 10%/year for existing oil), we only need 30 new Barnett Shale plays and 10 new Bakken Plays in order to maintain current US oil & gas production for 10 years.

The good news is, the world has plenty of expensive oil, so while it is expensive, there is plenty of it.

You can then copy the link and past it in your post inside an image tag(there is an Img button above the reply box that shows the format). I just did this yesterday for the same subject: total energy production from renewables. The fraction is not that small, 19% of global energy came from renewables. I posted on it here:C8 wrote:John A, Anti-doomer, I think you guys know that those amazing increases in renewables are from ridiculously low base rates. Anything looks impressive when you are starting from nearly zero. Renewables are still a very, very, small fraction of total energy production and no where near on pace to make a major transition any time in the next 2-4 decades. If I knew how to post an image on this site I would show you a chart of the amount of US energy produced by renewables (but I don't ).

Of course, the global decline rate from existing wellbores is probably closer to ExxonMobil's estimate of 4% to 6% per year. And in fact since 2005, global Crude + Condensate production has barely increased. If we subtract out condensate, which is a byproduct of natural gas production, actual crude oil production (less than 45 API gravity) has probably not shown any material increase since 2005.
westexas wrote:In any case, I don't see how anyone can argue that the overall decline rate from existing US wellbores has not dramatically increased, as more and more US oil and gas production comes from very high decline rate tight/shale plays.
westexas wrote: While Cornucopians are celebrating over what appears to be a continuing "Undulating Decline" in US crude oil production since 1970, for the average US consumer the reality is that global annual crude oil prices more than quadrupled from 2002 to 2012.

That's really the problem of Peak Oil isn't it? Where it's expensive people are having a harder and harder time to be able to afford it.
