| Abstract | The steamfield production piping size for the Kawerau geothermal power plant was determined by using predicted well performance and decline rates. The final steamfield configuration used six production wells. The design optimization was based on the test data from four wells, which was extrapolated to include both “normal” and “big bore” wells. A method of using the predicted well performance to determine the influence on steamfield piping size is reviewed. The method takes into account capital cost and make-up well drilling, and how this impacts net present value. |
