A SYSTEM FOR TRANSMITTING SIGNALS
A system is provided for transmitting signals between a sensor assembly contained in one or more well probes lowered into a well at the end of a cable and a surface control and recording unit. The cable includes a central line surrounded by several other lines and an external metal sheath. The trans...

| description | A system is provided for transmitting signals between a sensor assembly contained in one or more well probes lowered into a well at the end of a cable and a surface control and recording unit. The cable includes a central line surrounded by several other lines and an external metal sheath. The transfer of data from the reception assembly to the surface installation is provided by applying suitably coded signals between the central conductor and the external sheath. A considerable increase in the transmission flow rate of the cable is obtained. |
