Well integrity represents the comprehensive application of technical and organizational measures to prevent uncontrolled fluid release throughout a well’s lifecycle. In mature fields, aging wells face significant challenges such as corrosion, cement degradation, and formation compaction, all of which threaten mechanical and hydraulic barriers. Effective integrity management depends on the performance of critical components—casing, tubing, cement sheath, wellhead systems, and control instrumentation—supported by continuous monitoring through pressure testing and well logging. When failures occur, interventions using wireline, coiled tubing, and cementing operations restore barrier functionality. Compliance with international standards (API RP 90, ISO 16530, NORSOK D-010) ensures operational safety and environmental protection. Proactive surveillance, preventive maintenance, and the use of corrosion-resistant materials are key strategies to sustain well integrity and extend the productive life of aging wells.
