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.
Claims20
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;
- modifying that existing signal so as to encode information at the first location for opportunistic communication of that information to the second location;
- receiving the modified signal at the second location, and decoding the signal so as to retrieve the information.
The method according to claim 5, wherein the rectifier device is configured to rectify electric power for application of Impressed Current Cathodic Protection (ICCP) at the well structure.
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 a well structure between that first location and a second location;
- a signal controller configured, in response to the signal detector identifying an existing signal, to modify that existing signal so as to encode information at that first location for opportunistic communication of that information to a second location in that well structure, such a modified signal for receipt and decoding at that second location so as to retrieve the information.
A method of opportunistic communication of power 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;
- receiving the signal at the second location, and using power in the signal at that second location.
The method according to claim 20, wherein the method comprises modifying the identified existing signal to as to improve signal transmission of power to the second location.
Dependencies are inferred from the claim text.
