Abstract
Methods may include calculating a formation permeability for a subterranean formation from a combination of dielectric measurements and acoustic measurements, wherein the formation permeability is calculated according to the formula: k=a(Vσ/ε), where Vis either V, V, or V/V, σ is formation conductivity, Øis water-filled porosity, and a and b are constants that are empirically determined for the frequency selected with respect to V; and creating a design for a wellbore operation from the calculated formation permeability. Methods may also include obtaining a dielectric measurement from a downhole formation; obtaining an acoustic measurement from a downhole formation; and calculating a formation permeability from a combination of the dielectric measurement and the acoustic measurement.
