Tracers have not been utilized to their full potential due to their shortcomings (i. detection and recovery, and cost. Recently, there has been less emphasis on the study of tracers in terms of fluid flow in porous media. The science of fluid flow in terms of dispersion and permeability has not been focused to its full extent in the past decade.

This paper provides a novel perspective in the study of dispersion by observing velocity data as an indication of rock permeability, and presents experimental results and for tracer fluid flow in carbonate rocks. The analysis and interpretation is based on an experimental approach (setup, procedure and measurement), and mathematical analysis.

To gain a new perspective of studying the permeability and dispersion correlation, several chemical tracers are injected into three different carbonate core samples in a laboratory experiment. In this core flood experiment fluid is injected at different rates and is used to experimentally measure the dispersion coefficient at several given velocities.

Using the mathematical model permeability is determined and used in simulation to dynamically model the heterogeneity of the reservoir. The conclusion on estimating permeability from tracer expereiment.serve as input to simulation models, to enhancing characterization of reservoir.
