Well Integrity

Maintaining wellbore integrity throughout the life of the well is essential for production optimisation. The fundamental function of the well can be rapidly compromised by inadequate well design or construction and on a longer-term by tool failure or degradation of construction materials, which cause leak paths. Well integrity must therefore be accurately determined throughout the life-cycle of the well.

Accurately foreseeing problem areas enables prevention measurement to be selected wisely. Correct cement placement and protection is critical to ensure adequate mechanical support for the casing, safeguard against fluid corrosion, and isolate permeable zones at different pressures to avoid hydraulic communication. Corrosion monitoring and control is particularly important for deep or isolated wells, those producing CO2 or H2S, and wells that are envisaged to have long lifetimes.

Continuous downhole monitoring is therefore essential to identify any weak or failure points to prevent further damage and minimize repair expenses. It provides:

• Greater understanding of intervention or workover requirements.
• Significant saving in intervention and service costs.
• Considerable reduction in downtime and deferred production.
• Pro-active planning of resources.
• Any safety and environmental risks can be identified and managed to an appropriate level.
• Immediate identification and remedial action taken for any underperformance due to leaks or improper operation.
• In extreme events where integrity issues lead to plugging and abandoning the well (e.g. compaction, subsidence) the production engineer will have advance warning and will be adequately prepared to shut down the well in a controlled manner and also salvage expensive components from the wellbore.

Our job here at Tendeka is to provide you with our leading technology solutions to make your particular completion as continuously reliable as it can be. Our solutions will help you to monitor and protect downhole components that are critical to the integrity of the well, including the condition of the casing, casing cement, safety and control valves, ESPs, packers, and other in-well components which are integral to ensure maximum long-term production.
