ABSTRACT OF THE DISCLOSURE A method for determining at wellsites the swelling-clay content of shales and shaly sandstones by high-frequency dielectric measurements including: grinding a rock sample to a size suitable for testing; washing the rock sample with a fluid having a water activity substantially less than water, which may contain a soluble cation; packing the washed rock sample into a sample cell suitable for dielectric measurement; measuring the dielectric constant at a preselected frequency; and comparing the measured dielectric constant of the rock sample to calibration curves. A determination of the swelling-clay content may be performed at different levels depending on the nature of the samples to be compared. In the preferred embodiment, four levels of swelling-clay determination are possible. The first, or narrowest, level of determination may be used when the swelling-clay content of samples from a single site is to be determined. The second level of determination may be used when the swelling-clay content of samples from different sites which contain similar rock matrices is to be determined. The third level of determination may be used when the swelling-clay content of samples from different sites which contain varying rock matrices is to be determined. The fourth, or broadest, level of determination may be used when the swelling-clay content of samples of varying rock matrices is to be determined and the swelling clay are known to be interstratified with illite clays.
