The producing characteristics of vapor-dominated geothermal steam reservoirs bear some strong resemblances to those observed in hydrocarbon natural gas reservoirs. Consequently, many geothermal steam well tests are commonly analyzed using flow theory developed for the isothermal flow of hydrocarbon natural gases. Such analysis is most often made using the idealization of perfect gas fluid flow behavior in the reservoir. This study investigated the real gas flow characteristics of geothermal steam over the ranges of pressure, temperature, and noncondensable gas content commonly found in vapor dominated geothermal systems. Details of this study are available elsewhere (Mannon, 1977).
