Electrical conductivity property-parameter curves

All the macroscopic properties of the rocks depend on the microstructure and thus of porosity. It is clear that microscopic information is only partially accessible and fiom thoe comes the importance given to certain macroscopic parameters, which are mrasurable like porosity, specific surface, ftie curves of imbibition and drainage, the formation fictor (electric conductivity) and the permeability. We will ap xtadh here only the concepts essential fi>r comprehension of calculations.
