Fitting the Power Station to the Geothermal Field

Abstract

After the initial wells have been drilled in a new geothermal field there be sufficient information to develop a mathematical model of the field. If the model includes formulae giving well output as a function of wellhead pressure and the total fluid draw-off then calculations of station performance over a period of say 30 years can be made different station configurations or separator pressure conditions. exercises done to look at the feasibility of this type of analysis. model of the Wairakei field and the other on a partial of the Ngawha field. This paper presents results of two One is based on a It is concluded that the analysis is feasible and that it could be of assistance in determining the preferred station configuration and pattern of development .
