Abstract
A method and system of opportunistic communication in a well structure are provided. The method includes identifying at a first location an existing signal propagating in a section of the well structure between the first location and a second location; modifying that existing signal so as to encode information at the first location for opportunistic communication of that information to the second location; and receiving the modified signal at the second location and decoding the signal so as to retrieve the information.
Claims18
A method of opportunistic communication in a well structure, the method comprising:
- identifying at a first location an existing signal propagating in a section of the well structure between the first location and a second location;
- wherein the existing signal is a noise signal that comprises a series of harmonics;
- modifying the existing signal by modifying characteristics of the series of harmonics to produce a modified signal that encodes information at the first location for opportunistic communication of the information to the second location;
- and
- receiving the modified signal at the second location, and decoding the modified signal as to retrieve the information.
A system for opportunistic communication in a well structure, the system comprising:
- a signal detector configured to identify at a first location an existing signal propagating in a section of the well structure between the first location and a second location, wherein the existing signal is a noise signal that comprises a series of harmonics, and the signal detector is configured to detect the series of harmonics;
- and
- a signal controller configured, in response to the signal detector identifying the existing signal, to modify the existing signal by modifying the series of harmonics to produce a modified signal that encodes information at the first location for opportunistic communication of the information to the second location in the well structure, wherein the modified signal is configured for receipt and decoding at the second location to retrieve the information.
