Aim of WIEN
Helping operators optimise well intervention
performance:
Sharing aggregated and anonymised data
Sharing key learnings, lowlights/highlights
Collaborating on projects

Review
Key metrics - establish routine internal
performance review
Justification
WIEN benchmarking data across industry - justify
benefits of well interventions
Planning
Knowledge sharing and collaboration – get the relevant
details right
Execute
Through review, justification and planning - improve intervention
performance
Conclusions
13
12% total production contribution
Production protection 68% of interventions
Production restoration 60% of
production contribution
Twice as many gas Interventions
compared to oil
Technical success rate: 68% to 85%.
DHSV repairs: improve reliability
Onshore: test ground and transfer learnings
Subsea: fewest number/types but there
is a prize.
Variation in performance: share/learn
Future Areas of Focus
