    The porosity of a rock is the fraction of the volume of space between the solid particles of the rock to the total rock volume. The space includes all pores, cracks, vugs, inter- and intra-crystalline spaces. The porosity is conventionally given the symbolf, and is expressed either as a fraction varying

  • C1: Electrical resistivity of different soil and rock types

    Law states that the resistivity of a completely saturated whole rock (ρo) is given by m w o F = = φ− ρ ρ where F is called the formation factor, ρw is the resistivity of the pore fluid (water) and Φ is the porosity. On a log-log plot of oρ as a function of Φ, a straight line should result with slope –m.
