Chemostratigraphic data can be used to model and predict porosity and permeability data in sections where no core is available.
The chemical data is first compared with porosity and permeability data from a cored section. Once the relationships between the mineralogy and the pore/perm data has been established this data can then be applied to cutting sections to help predict porosity and permeability.
For instance if a carbonate cement is effecting the porosity and permeability the Ca levels should show a good trend with the pore/perm data.
