| Abstract | In fault dominated geothermal reservoirs, productive zones are developed along fracture systems of nearly vertical. Wells are drilled to penetrate this fractured zone where feed zones of both production and reinjection wells locate. A laboratory experiment for tracer test was conducted using a vertical two-dimensional porous media by changing depth and horizontal distances of feed points of wells. Color dye was used as tracer chemical and its color intensity was detected at the feed point of production wells and converted into concentration of dye with a color sensor. Tracer movement in the porous media was visually observed. |
