Abstract
Possible energy production from supercritical geothermal reservoirs has been studied in Iceland for over twenty years with conceptual thinking and analysis performed as part of the Iceland Deep Drilling Project (IDDP). Icelandic works on well output simulations have been conducted seeking to estimate the possible production capacity of a supercritical well. The forecasting from this simulation work, together with NZ wellbore simulation undertaken by GNS Science, is compared to the output of subcritical geothermal production wells from six geothermal fields in the Taupo Volcanic Zone (TVZ).
The flow test measurements from the IDDP-1 well undertaken between 2010 and 2012 were analysed and the output from this superhot well has been summarised and compared to the production well dataset.
This comparative analysis is documented in this paper where thermal and exergetic power are computed and compared.
