The Rotorua Geothermal Task Force - Preliminary Investigations

Abstract

A Task Force field has been established in Rotorua to of reducing the wastage of anergy. The existing level of fluid withdrawal from the field been to be t/d from enthalpy bores. reasons for the wastage have beer. Identified and current technology could be used to substantially the overall will be required this will cost several millions of for new reticulation piping, insulation, new heat and control devices. There is not a and cheap way of significantly reducing the drawoff satisfying the current heating requirements. It is also likely that most of low pressure bores will not at reduced as their production is already throttled so increased bore- sharing or group heating looks like an essential part of future in Rotorua. Downhole heat exchangers could a role to play.
