Strengthening Well Integrity with a Standards-Based System
An independent Lebanese upstream oil and gas company, operating Blocks 3 & 4 in the Sultanate of Oman, has achieved multiple discoveries and now produces over 28,000 barrels of oil per day (BOPD). With a growing portfolio of producing wells, the company recognised the need for a structured, standards-compliant Well Integrity Management System (WIMS).
The goal was to build a WIMS framework that aligned with ISO 16530-1 and anticipated Ministry of Oil and Gas (MOG) guidelines, while being practical and sustainable for internal teams to manage.
EnergyEdge’s Role
EnergyEdge was engaged to provide onsite technical support and system design. Our team worked closely with field and office personnel to develop the full WIMS structure and documentation, tailored to the company’s specific well types and integrity risks.
Key project activities included:
- Preparation of a WIMS framework aligned with ISO 16530-1 and MOG standards
- Review of all existing wells and development of a Well Integrity Severity Evaluation Ranking (WISER) database
- Creation of a Wells Failure Model with embedded risk assessments
- Drafting of a Company Wells Barrier Policy
- Development of Generic Well Barrier Diagrams for all well types
- Creation of detailed Well Integrity procedures, covering:
- Barrier verification
- Maintenance and testing
- Data recording and documentation
- Preparation of a RACI matrix for all integrity-related tasks
- Provision of a generic WIMS software tool and recommendations for bespoke platform options
Enabling System Ownership
After the onsite implementation, EnergyEdge provided continued remote assistance to review and refine documents developed by the client’s Well Integrity Focal Point. We also offered guidance on embedding WIMS ownership within the organisation, ensuring the system would be maintained and led by internal users—not external consultants.
Outcomes
- A full, ISO-aligned WIMS system tailored to the company’s well architecture and maturity
- Improved focus on critical wells through the WISER database
- Clear accountability and procedures for all well integrity tasks
- Increased capability and confidence within the client’s internal team to maintain and evolve the system
Conclusion
This project enabled the operator to move from ad hoc well management to a structured, transparent, and risk-aware integrity framework—supporting both safe operations and regulatory alignment across a growing asset base in Oman.
