BSP Fit for the Future: Success story this week
East Asset: Champion ESP Workover CP388 and CP382
Congratulations team!! Brilliant to see innovation & focus to delivery
What was the opportunity?
- Champion’s B2B3 project has 27 Electrical Submersible Pumps (ESP) installed
- BFD assumed Mean Time To Failure of 2 yrs
- To date many ESPs exceeded this:
4 wells> 3 years run-life
11 wells> 2 years run-life - CP388 failed due to sand production
- The opportunity was to bring back
- Furthermore, the team proactively looked at other ESPs that were operating outside design operating range.
- CP382 was identified to have high wear factor (verified by doing deadhead test)
- Team decided to perform proactive ESP change- out to realise about oil gain from ESP upsizing.
What did we do?
Story of many firsts for CP388:
- First Offshore ESP Workover with Hydraulic Workover Unit (HWU)
- First Workover executed successfully without CPRA requirement
- First Installation of Sand Screen with HWU
- First Mud Acid Job executed through HWU in Shell and by Halliburton in the region
The ESP in CP382 was changed-out and upsized.
All these were done within 6 months from opportunity identification to execution!
What was the outcome? What can we learn from this story?
Results:
- CP388 went on stream in March 2021 and is producing
- CP382 went on stream April 2021, producing which is and at minimum ESP Frequency (more to come).
Learnings:
- Sparing and Standardization of ESP pumps into two sets (key enabler for quick turnaround!)
- Well on stream about 2 weeks after x-mas tree landed with FRT and internal resources
- Operational philosophy amended based on corrosion logs acquired
- Extending production casing run life due to high CO2
