Maximising Water Injection System Performance
OPEX helped an oil and gas operator to maximise the performance of the water injection system on their North Sea asset. Here's how we did it.
Existing operational data was taken from the water injection system encompassing produced water, seawater filtration, sulphate removal package, deaeration and water injection pumps.
Every day, OPEX’s data scientists analysed 1 million data points and 10 thousand data relationships from this system.
Using predictive technology, data science and oil and gas domain expertise we focused on helping this customer to:
- Solve specific water injection challenges
- Reduce downtime
- Maximise the efficiency of the water injection system
During the first 20 months of application, we helped this customer to achieve:
water injection system trips avoided
hours of downtime prevented
of production revenue protected
bbls water injection protected
actionable insights were provided by OPEX
Typical examples of the types of issues that our data analysts helped to identify on this system:
- Early detection of faulty chemical probes preventing spurious outages
- Early detection of seal degradation across centrifugal pumps
- Effective management of SRP membrane & filter cleaning
- Pump performance monitoring
- Instrumentation fault detection
System Start-up Optimisation
The asset was experiencing difficulty re-starting a water injection pump and had called the OEM to help them offshore.
Before the vendor mobilised, the onshore team asked OPEX to investigate whether data science could be applied to address the problem. Our analysis revealed the chances of a successful start were more than doubled if the recycle valve position was restricted and if the pump’s motor was allowed to cool to a specific temperature before the attempt was made.
By applying this methodology, the pump successfully started first time, the OEM mobilisation was cancelled and the start-up procedures updated.
