Abstract
A device and method for estimating a concentration distribution of a fluorescent tracer in a low permeability medium is proposed. The device may obtain images by photographing acrylic boxes containing respective mixtures prepared by combining and stirring each type of clay with fluorescent tracer solutions. The device may also calculate a light intensity for the fluorescent tracer solutions for each clay, derive a light intensity of each RGB channel for each type of clay, select a channel representing a gradual change in the light intensity, and derive a concentration versus intensity equation of the selected channel. The device may further obtain images by photographing a flow chamber at an early stage and late stage of diffusion, estimate a fluorescent tracer concentration by using the concentration versus intensity equation, and evaluate validity of an estimation result by comparing the estimated fluorescent tracer concentration with a modeling value.
