An electromagnetic borehole telemetry system providing improved signal to noise ratio. Adaptive filters (74) use noise channels (68) as references to remove noise from the signal channel (66). Multiple noise channels are coupled to series connected adaptive filters (74) for removing each noise source from the signal channel. The order of noise removal is selected to remove the most significant first.

L'invention porte sur un système de télémétrie électromagnétique de trou de forage dont le rapport signal/bruit a été amélioré. Des filtres adaptatifs utilisent des canaux de bruit comme références pour éliminer le bruit du canal de signalisation. Plusieurs canaux de bruit sont couplés à des filtres adaptatifs connectés en série de façon à éliminer le bruit le plus important.
