Abstract
A communication assembly is described that when placed around a string casing in a wellbore transmits data along a pipe string from the wellbore to, for example, the surface of the well. The assembly includes a high magnetic permeability substrate to eliminate signal loss to the casing string thereby enhancing the signal and improving data transmission.
Claims24
A system for communicating from within a subterranean wellbore to the surface of the wellbore, comprising:
- a pipe string configured to be located within a subterranean wellbore, the pipe string comprising an exterior;
- and
- a coil communication assembly at a location along the pipe string, the coil communication assembly comprising:
- a transmission coil;
- and
- a high magnetic permeability substrate located between the exterior of the pipe string and the transmission coil.

A method for communicating between two locations in a subterranean wellbore including a pipe string comprising:
- sensing a condition of the wellbore;
- transmitting a signal indicative of the sensed condition;
- retransmitting the signal indicative of the sensed condition;
- preventing signal loss into the casing string during the retransmission of the signal;
- and
- receiving the transmitted signal at the spaced location.
