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 1):
A method for receiving electromagnetic (EM) telemetry signals, the method comprising:\n lowering a wireline into a first wellbore cased with an electrically conductive first casing, the wireline comprising one or more electrical conductors that extend longitudinally along the wireline from an uphole end of the wireline to a signal pickup, the signal pickup comprising a wireline electrode electrically connected to a first one of the one or more electrical conductors; electrically contacting the first casing with the wireline electrode; electrically connecting the wireline electrode to an EM telemetry signal decoder by way of the first electrical conductor; electrically connecting a reference electrode to the EM telemetry signal decoder; measuring, by the EM telemetry signal decoder, a potential difference between the wireline electrode and the reference electrode, the potential difference arising as a result of an electrical current induced in the first casing by the EM telemetry signals.
