Patent

CA 2692754

Disclosed herein is a method of canceling noise in a wellbore telemetry system. The method includes, acquiring at least one signal in the system, predicting at least one deterministic component of the at least one signal based upon a change of at least one deterministic component from past signal values, and subtracting the at least one predicted deterministic component from the acquired at least one signal.

L'invention concerne un procédé de suppression du bruit dans un système de télémétrie de puits de forage. Ce procédé consiste à acquérir au moins un signal dans le système, à prédire au moins un composant déterministe d'au moins un signal basé sur un changement d'au moins un composant déterministe des valeurs de signal passées, et à soustraire ce composant déterministe prévu du signal acquis.
