Abstract

A telemetry method transmits data from a downhole location to a surface location. During transmission an event is detected that makes it desirable to change a transmitted data stream. A downhole processor processes the detected event in combination with a predefined event database and downhole measurement data using a frame building algorithm to compute a digital data stream. Synchronization markers are added to the data stream to obtain a synchronized data stream in which the synchronization markers identify the detected event. The synchronized data stream is transmitted to the surface location using a downhole telemetry tool and received at the surface location to obtain a decoded data stream. A surface processor processes the synchronization markers to identify the detected event and further processes the detected event in combination with a predefined event database and the decoded data stream using the frame building algorithm to obtain the downhole measurements.
