Task
Keep control over a downhole pump when one of its sensors has failed.
Replacing the sensor requires lifting the equipment out of the well — that means stopping production and costly work.

signal without lifting the equipment
The model reconstructs the signal of the fourth sensor from the three working ones — the equipment does not have to be lifted out of the well.

What we did and how
We developed a virtual sensor — a model that calculates the readings of a failed sensor from the data of the three working ones.
- 01Analysis of historical pump telemetry
- 02Training and validating the model on actual readings
- 03Real-time signal calculation
- 04Monitoring model accuracy in operation
Result
4 of 3
signal without lifting the equipment
The pump keeps running under control, and there is no need to lift the equipment to replace the sensor.
