Abstract

The invention refers to an axial antenna structure for use on a borehole wireline or while drilling logging tool. The antenna comprises an insulating medium and an electrical conductor disposed on the insulating medium. The electrical conductor is situated to have a magnetic dipole moment parallel to a longitudinal axis of the borehole logging apparatus. A tri-axial configuration combines the axial coil design and at least one transverse antenna structure substantially co-located with the axial antenna. The transverse antenna structure has a magnetic dipole moment orthogonal to the magnetic dipole moment of the axial antenna.
