Petrophysics of magnetic dipole fields in an anisotropic earth.

Petrophysics of magnetic dipole fields in an anisotropic earth.

Measurement-while-drilling (MWD) resistivity log data are often acquired in highly deviated or horizontal holes. The loop sensors are located on the drill collar and are approximated as magnetic dipoles. The conductivity of the earth in the vertical direction σv and horizontal direction σh are almo...
