| Abstract | The potential for thermal cooldown from a petrogeothermal reservoir consisting of eight parallel hydrofractures spaced 50 meters apart has been estimated with two different models of heat transfer between the fractured massive and water circulated for heat extraction. One model is based on heat transfer processes for water circulating through the eight connected planar hydrofractures; the other is based on heat transfer processes for one dimensional flow through a well fractured rock block considered as a collection of spherical rocks of equivalent thermal radius. The results show good agreement between the two models and provide confidence not the range of parameters selected for the reservoir and the estimates of the lifetime of the petrogeothermal resource to a given abandonment temperature. |
