Computation and Interpretation of Miscible Displacement Performance in Heterogeneous Porous Media

Considerations of the interpretation of effluent concentration data obtained in flow through heterogeneous cores. Three models are used: Coats-Smith, porous sphere, and transverse matrix diffusion. A general analytical solution is developed by Laplace transformation, and the solutions are inverted by numerical methods. This result in a unique set of parameters for a given heterogeneous model. Criteria for design of laboratory experiments based on these results are suggested
