Abstract
The disclosure provides a method and system to recover some or all of the data missing in types of gaps that occur in data streams received via telemetry. The gaps can be filled in real time to enhance operator understanding of current operations. For gaps created by special sequences sent via telemetry during a time interval that telemetry would be sending measurement blocks (MB) of data, the gaps can be filled using special MBs combined with MBs for a next time interval to create combined MBs, sent via telemetry, and extracted to backfill the gaps. For gaps caused by corrupted data, the gaps can be filled with data from overlapping MBs having overlapping data based on overlapping time intervals. For gaps caused by gap events, including different drilling rates of penetration, event MBs with sampling rates different than a predetermined sampling rate can be sent via telemetry.
