Thanks for posting that .. I've often wondered if there was any geothermal potential from played out oil and gas wells .. The wells already exist and the geologic structures are characterized by a porous permeable rock layer with an impermeable cap rock layer .. sounds like the right sort of geology to extract low grade heat .. When following PO discussions I always see references to water flooding of nearly played out fields or oil and gas wells that are experiencing a high ( > 30% ) water cut .. Wonder what the water temps are ?? Try googling 'abandoned wells' .. There's 10s of thousands of them in the US alone .. Surely, a few are in the right sort of geologic structures to exploit for heat .. Even if it's not enough to generate steam it would be sufficient to power a stirling generator or provide space/district heating for an entire town .. Triff ..
