Logging means and methods are disclosed for distinguishing between dispersed and laminated clay in earth formations. A wireline apparatus is employed consisting of a multifrequency induced polarization logging tool operating at extremely low frequencies, combined with other logging tools which measure the total amount of clay in the formation. A determination is then made of the fraction of the total clay content in the formation which is due to laminated clay.
Apparatus for distinguishing dispersed and laminated clay in earth formations, comprising: induced polarization measuring means for making an induced polarization measurement of the dispersed clay content of a portion of such an earth formation; total clay measuring means for measuring the total amo
Apparatus for distinguishing dispersed and laminated clay in earth formations, comprising: induced polarization measuring means for making an induced polarization measurement of the dispersed clay content of a portion of such an earth formation; total clay measuring means for measuring the total amount of clay in the same earth formation; and combining means coupled to said measuring means for combining the results of said induced polarization measurement and said total clay measurement to determine the fraction of the total clay content in the formation which is due to laminated clay.
