Abstract
A system for communicating a signal between a tool and a signal processing unit includes a signal processing unit configured to at least one of transmit and receive the signal and a first cable coupled to the signal processing unit. The system further includes a tool having a second cable extending from the tool and configured to at least one of receive the signal transmitted by the signal processing unit and transmit the signal received by the signal processing unit, wherein signal is communicated between the first cable and the second cable by crosstalk.
Claims19
A system for communicating a signal between a tool disposed in a borehole penetrating the earth and a signal processing unit, the system comprising:
- a signal processing unit configured to at least one of transmit and receive the signal;
- a first cable coupled to the signal processing unit and disposed in the borehole wherein a production tubular configured to convey hydrocarbons is further disposed in the borehole;
- and
- a tool disposed in the borehole adjacent to the production tubular and comprising a second cable that is not in electrical contact with the first cable and extending from the tool and configured to at least one of receive the signal transmitted by the signal processing unit and transmit the signal received by the signal processing unit;
- wherein the signal is communicated directly between the first cable and the second cable by crosstalk without an intermediate device and the signal excludes at least one of guided waves and surface waves and the signal further excludes radio waves.
A method for communicating a signal between a tool disposed in a borehole penetrating the earth and a signal processing unit, the method comprising:
- at least one of (i) transmitting the signal from the signal processing unit connected to a first cable disposed in the borehole to the tool having a second cable that is not in electrical contact with the first cable and extending from the tool and (ii) receiving the signal from the tool using the signal processing unit, the tool being disposed in the borehole adjacent to a production tubular configured to convey hydrocarbons;
- and
- at least one of (iii) receiving with the tool the corresponding signal transmitted by the signal processing unit and (iv) transmitting with the tool the corresponding signal received by the signal processing unit;
- wherein the signal is directly communicated between the first cable and the second cable by crosstalk without an intermediate device and the signal excludes at least one of guided waves and surface waves and the signal further excludes radio waves.
