The influence of magnetic permeability and dielectric constant in induction logging

The Influence of Magnetic Permeability and Dielectric Constant in Induction Logging [Pg.299]

In principal the quasistationary electromagnetic fields applied in induction logging depend on conductivity and magnetic permeability. For this reason an investigation of the influence of the magnetic permeability can be of great practical interest, specially for two [Pg.299]

Results of analysis of the influence of the magnetic permeability described in this section are based on results of calculations of the magnetic held on the borehole, when an invasion zone is absent. [Pg.300]

Let us first consider some features of the influence of /.t in a uniform medium. [Pg.300]

As was shown in Chapter 2 the electromagnetic field of the magnetic dipole can be presented as [Pg.300]
