Yes, I'm aware that fracking is not new, but the unprecedented drilling
rate is new, and the dropping returns on effort are very new.
So not just net energy is dropping due to dropping EROEI, the
liquid volume yield/effort is dropping. This is the novel piece of
bad news. I'm really really interested in how fast the coal EROEI
drops, and I genuinely hope it's not dropping as fast as tight oil and gas.
It's a real pity The Oil Drum has shut down with no single stop
shop left, as it was a great source of up-to-date data you could't
get from the horse's mouth. Now one has to scrounge around, and I
don't really have time for that. Despite all appearances to the contrary ;)

I don't know anything about producing from shale, other than what everybody knows - that fluid is pumped in to crack the shale and increase the surface area from which the oil can bleed into the hole from which it is pumped.
