Shield apparatus for use in conjunction with a well tool andmethod for shielding a coil

A shielding device for use in conjunction with a tool for drilling wells and the process for shielding a coil shielding device for use in conjunction with a tool for drilling wells to selectively attenuate one or more components of the electromagnetic energy field insofar as The component interacts with the shield. The shield is composed of a flexible strip or conductive body and comprises at least one inclined slit or inclined conductive element therein. The shield being adapted to enclose an antenna mounted on a tool for drilling wells. A method for rotating the magnetic dipole axis of a transmitter or receiver coil. A process for winding and shielding an electric coil such that the resulting coil emits or receives selected components of the electromagnetic energy field.
