Abstract
We conducted tracer experiments using a two-dimensional porous medium modeling a vertical fault system. The medium has a dimension of 600mm long, 1500mm wide and 20mm thick, and was filled with glass beads of 1mm diameter. In order to visually observe the tracer movement in the model, we injected dyes as tracer materials. We developed an optical tracer concentration sensor for concentration measurement on the basis of absorption spectrophotometry method. The sensor was located at the outlet of simulated production well. Simultaneous injection of different tracer dyes at two reinjection wells was conducted and concentrations of each tracer were successfully measured at the production well with this newly developed sensor.
