Abstract
A system that is positionable in a wellbore in a subterranean formation can include a first transceiver that is positionable external to a casing string in the wellbore. The first transceiver can wirelessly transmit data via a signal within a frequency band that is selected based on a fluid property of a fluid in the wellbore and a property of the subterranean formation. The system can also include a second transceiver that is positionable externally
Claims20
A system that is positionable in a wellbore in a subterranean formation, the system comprising:
- a first transceiver that is positionable external to a casing string in the wellbore for wirelessly transmitting data via a signal within a frequency band that is selected based on a fluid property of a fluid in the wellbore and a property of the subterranean formation;
- and
- a second transceiver that is positionable externally the casing string and operable to receive the signal.
A communication system that is positionable in a wellbore, the communication system comprising:
- a first transceiver that is positionable external to a casing string in the wellbore for wirelessly transmitting a signal in a frequency band that is selected based on a fluid property of a fluid in the wellbore and a property of a subterranean formation;
- and
- a second transceiver that is positionable external to the casing string for receiving the signal, extracting data from the signal, and relaying the data to a third transceiver using another frequency band.
A method comprising:
- receiving, by a transceiver that is external to a casing string, a sensor signal from a sensor operable to detect a fluid property of a fluid in a wellbore and a property of a subterranean formation;
- determining the fluid property of the fluid based on the sensor signal;
- determining the property of the subterranean formation based on the sensor signal;
- selecting a frequency band based on the fluid property and the property of the subterranean formation;
- and
- wirelessly transmitting data via a signal within the frequency band.
