The programmable Welltec® Data Monitoring (WDM) solution measures and records pressure and temperature (data) within the liner or casing annulus onto which it is mounted. The WDM is battery powered with programmable memory, an operates autonomously from surface, recording data 24/7. Battery life is a function of the BHT, sampling and download frequency. The recorded data is downloaded using the wireline deployed Welltec® Data Reader (WDR™). The WDM is identified and activated by the wireless telemetry from the WDR and transmits the data quickly through the wall of a single tubular string to the WDR with SRO (surface read-out).
The wireline WDR intervention can be combined with other services such as CBL, PLT, etc.
