Design and Implementation of a Digital Twin for Live Petroleum Production Optimization
Fig . 3 : Data variety – Sensor Data , Metadata .
These sensor signals were collected through wellsite telemetry and dropped onto a cloud based storage by the well operator ’ s SCADA provider . This data was typically accessed by the operator for monitoring and surveillance . The sensor data is universally accessible once access credentials are shared for data transfer . Such data is time-series data and is typically transferred in files titled after a time-stamp , and containing the sensor signal for all the assets during a chunk of time . It might be worth noting that the sensor streams can be intermittent due network or telecommunication issues , delivered out of order or on a time delayed basis . These time-specific files can be aggregated and restructured to tables as suited by the user . In this particular case , this data was converted to tables indexed by asset ID and timestamp ,
