| Abstract | All available data related to the Te Aroha low enthalpy geothermal system were collated and analysed. The geothermal system produces low temperature bicarbonate and mineral-rich fluid, historically used directly for drinking and bathing, although drinking the water is now discouraged. To extract higher quantities of fluid from the system to satisfy the demand, bores have been drilled within the domain. As of 2014, there are three geysering (selfdischarging) bores, within the Domain, and geysering is driven by the release of carbon dioxide gas from solution. The Te Aroha Domain is a historic area with collected data dating back to 1889. The data can be used to determine how the system has been affected by exploitation. All the relevant studies conducted on the Te Aroha domain have been analysed to gain a further understanding of the geothermal system. This work gives an insight into the geological setting of the geothermal resource and models and interprets the system using the available wellbore pressure and temperature data. |
