Chris: if you utter "reservoir" - you are on the wrong track. Nothing must "COME OUT" from the depth. Not even what YOU pumped in into open plenum. (My objection against the NZ plant). In Hungary in the 1950s a 'hot spring well' was tried to bring out 'heat' by its own pressure. By the time it reached the surface cooling a bit (and expanded(!) from the pressure) the M U D solidified into a hot mass. There was no private enterprise in commi Hungary at that time, so the idea was scrapped. John M
