Thanks for the info. The production data (together with the drilling record) certainly suggests there was a technological breakthrough somewhere along the line. EROI can actually go down, rather than up!

But politically, the idea of supporting higher natural gas prices would be difficult. It would probably have to be put in place with production controls, that would gradually change over time, as new infrastructure was added. Not likely to happen.

Hm, Gail, I don't know if RM is saying that.
He says more fracing is taking place, greater investment despite fewer wells.

Added in edit: RM says

A little good news for the operators: less wells drilled but much more expensive due to multistage fracs.

How that nets out on energy seems unclear.

Still, fascinating post.
