The production of natural gas in the US has not been increasing for about two years. Fitted with a Gaussian function, it shows a peak in the second half of 2012 and, from then on, a tendency to decline. Decoupled in its various components, the data show that shale gas production is still increasing, but not fast enough to compensate for the decline of conventional gas production.
Are we already seeing the end of the "shale gas revolution"? It is too early to say but, surely, these data agree with the viewpoint of those who had been seeing the whole story as a short lived financial bubble. (see, e.g., a recent series of statements by Arthur Berman)
