Stabilizing Process Conditions

Notification Algorithm - Trigger

We monitor Operations and provide Assistance

Notification Algorithm - Trigger

These situations can typically occur when producing from unstable wells

Stabilizing Process Conditions

24

Operational Experience

With Real-time data we can be an equal discussion partner with the

Operator during trouble shooting and operational monitoring

We can work together 24-7, avoid unnecessary stops / wear and

tear on the pumps & reduce downtime

Improved operating procedures are made on the basis of historical

data

The AVAILABILITY of the pumping systems has been considerably

improved since we started with FRIEND

We compare the performance for different pumping systems in

operation when assessing the overall condition of the pumps
