Well Integrity Assessments and Audits

TwinHorizon Solutions supports operators in conducting independent well integrity audits and assessments to evaluate the condition and performance of well barrier systems throughout the well lifecycle. These activities help identify integrity risks, verify barrier compliance, and define appropriate remediation actions. Audits and assessments typically include:

• Review of well schematics, well design documentation, and barrier architecture.
• Evaluation of well integrity standards, policies, procedures, and operational guidelines against industry best practices and international standards.
• Analysis of pressure monitoring data, including sustained annulus pressure (SAP) trends and diagnostics.
• Assessment of barrier design and verification against company requirements.
• Review of integrity testing results, including pressure tests and barrier verification records.

The outcome is a structured evaluation of well integrity status, identification of potential failure mechanisms, and practical recommendations for maintaining or restoring barrier integrity.
