Complete wellhead maintenance management
Our offer covers management, field crews, equipment, consumables, and a comprehensive document package—so preventive and integrity maintenance is coordinated end to end rather than handled as ad-hoc callouts.
Routine maintenance
Routine work follows a method agreed with the client and is typically scheduled every six or twelve months. Standard activities include valve servicing, pressure and function testing, visual inspection, and record keeping.
- Flush, lubricant, and sealant injection to Christmas-tree and annulus valves
- Pressure or inflow testing and function testing of tree and annulus valves
- Pressure testing of casing hanger / pack-off voids
- Valve actuator operation and testing
- Annulus-pressure recording
- Visual inspection of wellhead and Christmas-tree assemblies
- Wellhead as-built drawing compilation
- Computerized storage of service records
Non-routine maintenance
Non-routine work addresses items that are no longer fit for purpose. Tasks are planned to minimize production deferment and clashes with other site activities, and can include installation, refurbishment, repair, and inventory reporting.
- Hot tapping services
- Valve drilling services
- Casing cutting services
- Specialty sealant services
