Patent ID: 8872670

Claim:
A method for transmitting information with a compliant medium in a wellbore extending below ground from a surface location, the compliant medium comprising a wire extending from a first point which is at the surface to a second point which is below ground and onwards towards a termination below ground, the method comprising steps of: biasing the wire, wherein the biasing is performed by applying tension to the wire at the first point which is at the surface; intermittently gripping the wire at the second point which is below ground so as to restrain the wire at the second point against displacement by the applied tension, wherein: the first point is distant from the second point, and the intermittent gripping modulates information onto the wire; making measurements of one of a magnitude of displacement or a rate of displacement of the wire at the first point which is at the surface, in response to the applied tension, so as to observe changes in compliance of the wire resulting from the intermittent gripping of the wire at the second point, and recovering the information from the measurements.
