Abstract EN
Electrokinetic phenomena link fluid flow and electrical flow in porous and fractured media such that a hydraulic flow will generate an electrical current and vice versa.
Such a link is likely to be extremely useful, especially in the development of the electroseismic method.
However, surprisingly few experimental measurements have been carried out, particularly as a function of frequency because of their difficulty.
Here we have considered six different approaches to make laboratory determinations of the frequency-dependent streaming potential coefficient.
In each case, we have analyzed the mechanical, electrical, and other technical difficulties involved in each method.
We conclude that the electromagnetic drive is currently the only approach that is practicable, while the piezoelectric drive may be useful for low permeability samples and at specified high frequencies.
We have used the electro-magnetic drive approach to design, build, and test an apparatus for measuring the streaming potential coefficient of unconsolidated and disaggregated samples such as sands, gravels, and soils with a diameter of 25.4 mm and lengths between 50 mm and 300 mm.
