Well Barrier Surveillance
This service provides data and measurements required for classifying and risk ranking wells with sustained casing pressure (SCP).
A complete integrated system for testing and monitoring the integrity of well barrier elements secures a cost-effective service and immediate results.
Applications
- Trouble shooting Sustained Casing Pressure (SCP)
- Health check surveillance on scheduled or exception basis
- Well Abandonment - Testing barriers before, during and after the P&A operation
Deliverables
- Gas storage volumes in the evaluation of the annuli and potential for uncontrolled release of hydrocarbons.
- Level of hazardous and corrosive components in annular volumes
- Gas, liquid and combined leak rates
- Potential sources, mechanism and location of the leaks
- Historical access and trending of test results
- Well classification and ranking on request
Benefits
- Identify source and potential consequences of degraded well barriers early in the well life cycle
- Avoid unplanned shutdowns
- Keep track of individual well results and trends
- Determine suitable schedule for repairs and/or replacements
- Increase Production over field life
- Extend the life cycle of wells by minimizing stress on well barriers during testing
- Cost effective well integrity surveillance over field life
- Surface deployed service, which require no shut in of wells or intervention
- Minimal interruption to platform activities
- Well integrity status and history known up to abandonment
