The telemetry module is the uppermost tool in the stack. Its main function is to collect and combine digital data from all the other tools and to transmit this in a digital form via the logging wireline to the surface acquisition system. It also provides control functions and tool power to the other logging
tools. The tool includes natural-gamma, CCL, mud-resistivity and borehole-tilt measurements.
All tools in the stack communicate with the telemetry module over common internal RS485 data buses. The telemetry module organises this data and transmits it to the surface digitally using a high-speed proprietary RG protocol. Data is acquired on a depth basis with a sample interval that can be selected to optimise measurement resolution and/or logging speed.
