... ABSTRACT Clay and framework mineralogy, determined from geochemical well logging, are used with porosity to estimate the intrinsic permeability of elastic formations. The mineral abundances are first combined with their individual grain densities to yield a continuous matrix density log which...

However, lithology was not well organized in mineralogical model due to the complex texture. Therefore, the formation volumetric model was updated using lithological concept by ELAN based on VSH from SP...

...). At a permeability around 0.1 mD, the porosity varies between 50% and 30% for pure kaolinite and pure silt samples. At same permeability, the variations of porosity in other silt-kaolinite mixtures are also significant. Therefore, permeability estimation from porosity without considering mineralogy will introduce...
