For a model of a lumped parameter reservoir combined with production wells, changes of production flow rates were calculated. From the results, followings can be said; 1. the flow rate steeply decreases just after the start of production until the reservoir reaches to the saturated condition, and then, 2. it keeps nearly constant for a while and abruptly declines in non-reinjection case, though it gradually decreases in the case of reinjecting low temperature water, and 3. if the fluid influx from heat source is large enough for the reservoir to keep unsaturated condition, it keeps constant for a long time, over 1 × 105 hours.
