| dc.description | Abstract: Electrokinetic streaming potentials were measured in typical geological materials using specially constructed apparatus to model water flow through subsurface flow paths. The apparatus used for the study is described by this report as are the measurement techniques used. Comparisons between the observed electrokinesis phenomena and theoretical predictions are made. Conclusions resulting from this study include: (1.) Studies of streaming potentials in typical geological materials should be concentrated in real geological environments. (2.) Fluid electrical resistivity as influenced by dissolved ion content is more critical to streaming potential measurements than temperature influences and should be measured directly. (3.) Contrary to the results of past studies of streaming potentials, it was found that metallic electrodes performed more satisfactorily than did nonpolarizable porous pot electrodes. (4.) A relationship was observed between the flow rate of the water through the porous media and the electrical surface potential of the solid portion of the media. This relationship may provide a useful application of streaming potential surveys after further development. (5.) The presence of appreciable amounts of clay in or near the water flow path through porous media degrades electrokinetic potential magnitudes and hinders streaming potential measurements. | - |
