Every well has two barrier envelopes between the reservoir and the environment. The primary envelope typically includes the completion, packer and tubing; the secondary includes the casing, cement, wellhead and the valves that close on the annulus. Loss of one envelope is an anomaly that must be managed; loss of both is a containment failure. A well barrier schematic is the document that records which element does what, and it is the foundation of integrity management.

Threats accumulate over the life of a well. Corrosion thins the tubing, cement degrades, elastomers age, valves seize, and annulus pressures appear where they were not expected. Most of these are slow and detectable, which is why monitoring and periodic testing matter. Integrity failures rarely arrive without warning; they arrive after warnings that were recorded but not acted upon.

The management system is what turns individual checks into control. It defines acceptance criteria for each barrier element, the frequency of testing, what constitutes an anomaly, who decides whether a well keeps producing and what the escalation route is. Without that structure, integrity work becomes a set of unconnected activities and the accountability for a well's status is unclear. This course covers both the engineering and the system.

By the end of this training, participants will be able to:

• Explain well barrier philosophy and the primary and secondary barrier envelopes.
• Construct and maintain well barrier schematics.
• Apply the ISO 16530 framework across the well life cycle.
• Identify integrity threats and failure modes for each barrier element.
• Define acceptance criteria and testing requirements for barrier elements.
• Plan and interpret integrity monitoring, testing and inspection programmes.
• Classify wells by integrity risk and apply the resulting operating restrictions.
• Manage anomalies, including assessment, mitigation and escalation.
• Specify integrity records, data systems and reporting.
• Build and run a well integrity management system with defined roles and competence.

Organisations sending participants to this training will:

• Reduce the risk of loss of containment and its consequences.
• Meet regulatory and standards requirements for well integrity.
• Identify and manage integrity anomalies before they become failures.
• Make well integrity status visible and accountable across the organisation.
• Extend safe well life and support informed decisions on continued operation.

Participants will:

• Understand barrier philosophy and be able to build well barrier schematics.
• Know what ISO 16530 requires at each life cycle stage.
• Be able to define acceptance criteria and testing programmes.
• Be able to assess and manage integrity anomalies.
• Be able to contribute to or run a well integrity management system.

• Well integrity engineers
• Production engineers
• Completion and well engineering staff
• Well intervention engineers
• Operations engineers and supervisors
• Technical authorities and regulatory compliance staff

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
