ABSTRACT:
Example wellbore telemetry systems and methods for transmitting signals between a surface unit and a downhole tool are disclosed. One example method transmits data between a downhole location in a wellbore and a surface location associated with the wellbore by measuring downhole data via at least one downhole component and generating a data frame containing at least a portion of the downhole data. The example method varies a telemetry bandwidth allocated to the at least one downhole component in response to the at least some of the downhole data corresponding to a special event and transmits the at least some of the downhole data to the surface location via the telemetry bandwidth allocated to the at least one downhole component.
