Title: IMPROVEMENTS IN OR RELATING TO GEOTHERMAL POWER PLANTS
Abstract:
A geothermal power plant and method of operating a geothermal power plant in which control over the creation and growth of fractures in the geothermal formation is achieved. A downhole pressure gauge (14) with a high data acquisition rate is located in the injection or production well. Pressure changes in the well are recorded as a pressure trace and transmitted to the surface as data. The data is analysed to determine fracture parameters of the geothermal formation. The pump rate of the well is then varied in response to the calculated fracture parameter(s).
