Geothermal reinjection is being used to counteract pressure draw-down, i.e as artificial water recharge, and to extract more of thermal energy in reservoir rock (Stefansson, 1997; Axelsson and Gunnlaugsson, 2000). Cooling of production wells or thermal breakthrough, is one of the main disadvantages associated with injection. Tracer test is used to predict possible cooling of production wells due to long-term reinjection of colder fluid through studying connections between injection and production wells.<p> <br /> <br /> <br /> Tracer test involve injecting a chemical tracer into a hydrological system and monitoring it's recovery, through time at various observation point. Tracer modeling is nonlinear cases. This model used to estimate average fluid velocity in the channel and dispersion coefficient with Nonlinear Least Square(NLS) methode.<p> <br /> <br /> <br /> By using nls methode wll get the estimate value for average fluid velocity in the channel and dispersion coefficient, based on the data from wells AH-4bis, AH-19, AH-22 in Ahuacapan, Elsavador.
