Abstract
Deep exploration drilling and well testing conducted during the last decade have demonstrated that a high temperature geothermal resource is associated with the Kilauea East Rift Zone. Results obtained to date suggest that the dike system forming the rift provides a source of heat and is the primary mechanism for control of the hydrology within the geothermal system. Mineral deposition from seawater may also play a role in the exclusion of saline fluids from the deeper portions of the rift. The data presently available indicate that the hydrothermal system associated with the Kilauea ERZ has a sharp boundary to south and a more gradual one to the north. Projection of this model to older volcanic systems suggest that higher temperatures will be present in reservoirs having seawater recharge and lower permeability.
