TLDR
The regression equation for the volcanic rocks was found to provide satisfactory predictions of log(D(m)/D*) for other types of rocks with similar ranges of matrix porosity and permeability as the volcanic rock matrix samples, but it did a poorer job predicting log(M/D) for rocks with lower porosities and/or permeabilities.About:

Effect of density-driven flow on the through-diffusion experiment.
TL;DR: To evaluate the effect of density-driven flow, a through-diffusion experiment was conducted for KCl and KI aqueous solutions with various densities, and a theoretical model using a diffusion-advection equation including Darcy's law is presented.

Development of Models to Simulate Tracer Tests for Characterization of Enhanced Geothermal Systems
Mark D. Williams,Paul W. Reimus,Vincent R. Vermeul,Peter Rose,Cynthia Dean,Tom B. Watson,Dennis L. Newell,Kevin Leecaster,Eric M. Brauser +8 more
TL;DR: In this article, a tracer and tracer interpretation tool for geothermal systems is presented. But the focus of this project was initially focused on tracer development with the application of perfluorinated tracer (PFT) compounds, non-reactive tracers used in numerous applications from atmospheric transport to underground leak detection, to geothermal system.

The electrical resistivity log as an aid in determining some reservoir characteristics
TL;DR: The usefulness of the electrical resistivity log in determining reservoir characteristics is governed largely by: (1) the accuracy with which the true resistivity of the formation can be determined; (2) the scope of detailed data concerning the relation of resistivity measurements to formation characteristics; (3) the available information concerning the conductivity of connate or formation waters; and (4) the extent of geologic knowledge regarding probable changes in facies within given horizons, both vertically and laterally, particularly in relation to the resultant effect on the electrical properties of the reservoir as mentioned in this paper.

Diffusion in the rock matrix: An important factor in radionuclide retardation?
TL;DR: In this paper, the authors analyzed the accessibility of the rock matrix to radio-nuclides and showed that the diffusion of the nuclides into the rock matrices and their sorption onto the surfaces of the microfissures are the main mechanisms retarding migration from a repository.

Contaminant Transport in Fractured Porous Media: Analytical Solution for a Single Fracture
TL;DR: In this paper, a general analytical solution is developed for the problem of contaminant transport along a discrete fracture in a porous rock matrix, which takes into account advective transport in the fracture, longitudinal mechanical dispersion in a fracture, molecular diffusion along the fracture axis, adsorption into the face of the matrix, adhesion within the matrix and radioactive decay.
