| Abstract | Recent field experiments in Japan have emphasized the importance of performing tracer tests in any geothermal utilization in which reinjection is in use or is planned. This is because rapid short circulating between reinjection and production wells may occur due to the fractured m=nature of the system. in cases where fracturing is such that preferred pathways exist in the reservoir, the result may be a raid thermal drawdown of the field production. Tracer testing provides a method of evaluating the magnitude of such problems. Previous methods used to analyze the Onuma, Hatchobaru, and Otake tracer tests have uses early and long time data, this paper discusses the use of the field concentration/time profile in fractured systems. |
