Journal Article: Roosevelt Hot Springs Reservoir Model Applied to Forecasting Remaining Field Potential

Abstract
The Roosevelt Hot Springs geothermal fieldhas maintained a capacity of approximately 25megawatts (gross) since 1984. Ten years of field dataand reservoir pressure history are used to calibrate acomputer model of the Roosevelt geothermalreservoir. The basic features of this model aredescribed, and the history matching process isreviewed. The model is used to estimate theremaining potential of the field in terms of capacityversus sustainability. Wellhead pressure is used asthe pressure constraint in the forecasts. Thesesimulations indicate that the current capacity of 25megawatts is sustainable throughout the forecastperiod (to the year 2026), and that a capacity of 50MW is sustainable for 18 years. Higher capacitiesdecline sooner, but all decline rates decrease towardasymptotic limits approaching 40 MW of capacity.
