Abstract
The flow of water in an Engineered Geothermal System (EGS) is an issue of considerable importance for the emerging Geothermal Industry. A steady-state mathematical model was developed for the purposes of modeling water flow through horizontal fractures of an EGS. Using classical fluid mechanics the model provided approximate values of reservoir pressure drop, injection wellhead pressure and production wellhead pressure. The model has enabled the Petroleum and Geothermal Group of the Department of Primary Industries and Resources of South Australia (PIRSA) to carry out sensitivity studies. PIRSA has used the model in its evaluation of the technical feasibility of EGS in the Cooper Basin in South Australia.
