Abstract:
A retrievable receiver for electromagnetic telemetry signals originating from a first wellbore is located in a second wellbore. The receiver uses a casing of the second wellbore as an antenna. A signal pickup unit is provided on a multi-conductor wireline in the second wellbore. The signal pickup provides sensors (e.g. electrodes) for detecting signals at plural locations along the second wellbore. Signal reception can be optimized by adjusting the position of the wireline in the second wellbore and/or selecting sensor(s) for use in receiving the telemetry signals. The receiver may lack any active electronics in the second wellbore.

Claim (Index 14):
A system for receiving electromagnetic (EM) telemetry signals, the system comprising:\n a wireline deployable into a first wellbore comprising a first casing, the wireline comprising one or more electrical conductors extending longitudinally along the wireline from an uphole end of the wireline to a signal pickup on the wireline, the signal pickup comprising a wireline electrode electrically connected to a first one of the one or more electrical conductors of the wireline; a reference electrode; and an EM telemetry signal decoder connected at an uphole end of the wireline, the EM telemetry signal decoder having an input electrically connected to the wireline electrode by way of the first electrical conductor of the wireline and electrically connected to the reference electrode, the EM telemetry signal decoder configured to monitor a potential difference between the wireline electrode and the reference electrode; wherein the wireline electrode is adapted to electrically contact the first casing when the signal pickup is deployed into the first wellbore.
