A solution of a clay material is pumped through a sample of a porous material. After completion of pumping, at least a part of the sample is crushed into powder and a clay fraction is elutriated from the prepared powder. X-ray diffraction analysis of the elutriated clay fraction is performed and weight concentration of clay material in the sample of the porous material is determined.
