Abstract
A numerical model of the geothermal fields in the Taupo Reporoa Basin is discussed. The geothermal fields included in this model are: Atiamuri, Horohoro, Ngatamariki, Ohaaki, Ongarato, Orakeikorako, Reporoa - Golden Springs, Te Kopia, Waiotapu-Waikite and Waimangu. The model is made deep enough (6kms) so that the whole of the convective systems fit within the model. The aim of this study is to investigate the deep structure and dynamics of these fields and their inter connectivity. The model correctly predicts the location of geothermal plumes for the aforementioned fields, their shallow heat and mass upflows and the temperatures in the upflow zones at about 3 km. The permeability structure and heat source distribution are the main parameters varied in the calibrating the model.
