Barnes, D. E.; Caffey, T. W.H.

During an in-situ energy extraction process, a continuous knowledge of the temperature profile through the combustion area is desirable for analysis and control. To provide this data, a telemetry system has been developed that will monitor the thermocouples from beneath the process bed, digitize the data into 12 bit words and store them into memory. Every six hours, the stored data is transmitted laterally through the earth to a receiver outside of the high temperature zone and then sent to the surface by wire where it is stored on magnetic tape and processed and displayed on a Texas Instruments Silent 700 terminal.
