Intervention Performance Ltd. provides senior well intervention and light well intervention (LWI) expertise to Operators delivering complex offshore, subsea, and mature-asset programs worldwide.
We support planning, readiness, execution oversight, and optimization across conventional and subsea interventions — ensuring operations are technically sound, safely executed, and cost-effective.
Support is focused on light well intervention and well intervention programs where execution success depends on realistic candidate selection, pressure and barrier management, and disciplined scope definition. Engagement is provided as senior technical assurance and execution challenge, operating within the operator’s technical authority framework, barrier policy, and regulatory obligations.
• LWI is appropriate where well conditions, barriers, and pressure envelopes are fully understood and execution margins are clear.
• Where well integrity uncertainty, access limitations, or pressure risk exceed defined escalation thresholds, rig-based intervention or alternative execution methods are required.
• Intervention Performance does not position LWI as a replacement for drilling rigs, but as a disciplined option within a broader well lifecycle strategy.
Operators engage us to strengthen intervention delivery where risk, complexity, or consequence is high.
Our support includes:
Intervention concept selection and program development
Subsea and riserless LWI planning and execution support
Barrier philosophy, integrity assurance, and compliance
Vessel readiness reviews and offshore execution oversight
Interface management between Operator, vessel, and service providers
We operate as embedded senior SMEs, providing judgement, challenge, and decision support — not generic reporting.
