Does anyone recall coming across a detailed discussion of the rationale for the HEWI concept anywhere? I spent quite some time on the weekend thinking about it and couldn't come up with any sort of intuitive understanding of why this might be a good idea - in fact every way I looked at it made it seem a really daft idea! The again, second year Thermodynamics was my worst subject so maybe I'm missing something blindingly obvious. Had a quick look on the site and couldn't see anything.
I'm hoping it's not just code for "we couldn't make the numbers work out if we drilled to 6000 metres" :-)
It seems especially odd when you put it in the context of GDY going so far out on a limb (well away from the transmission lines) in order to get to rocks a few 10s of degrees hotter. If there is a cogent argument for that surely there is a similar argument for PTR (who are closer to the lines) to get a few extra 10s of degrees by going deeper???
I recognise that an 8" bore past 4000 metres may be pushing the technology but the way I read the Petrathem dox it seems like they see having their reservoir in the insulaing layer as a plus, not a compromise.
Not a downramp (I continue to hold about as much in PTR as in GDY) - genuinely interested as this seems a large philosophical difference between the companies.
