Well Integrity Management System Implementation
Project Overview
Following changes to state-based regulatory requirements, an Australian onshore operator required the development and implementation of a formal Well Integrity Management System (WIMS) to ensure compliance with statutory obligations and improve oversight of well integrity across its asset base. JJM personnel were engaged to design, implement and operationalise the WIMS and undertake a comprehensive integrity review of the operator’s well stock.
Project Details
Locaiton: Queensland, Australia
Industry: Conventional Oil and Gas
Scope of Work
Development of a Well Integrity Management System aligned with statutory requirements and industry standards
Implementation of the WIMS as an approved operational framework for the operator
Review and analysis of the operator’s full well stock using a proprietary well integrity database system
Engineering assessment of each well’s integrity status based on well type, corrosion risk and barrier test results
Evaluation of well-specific Maximum Allowable Annulus Surface Pressures (MAASP) and Maximum Operating Pressures (MOP)
Development and implementation of a scheduled well integrity testing program
Preparation of well-specific remediation plans and fitness-for-service assessments
Development of individual Well Integrity Management Plans and escalation workflows in accordance with WIMS requirements
Key Challenges
Integrating well integrity processes with existing operational and data management systems
Assessing integrity status across a diverse well stock with varying ages, well designs and operational histories
Interpreting historical integrity data, barrier tests and corrosion risk indicators to determine current well condition
Implementing consistent integrity monitoring and escalation processes across the operator’s well portfolio
Outcomes
The project successfully delivered a compliant Well Integrity Management System and established a structured integrity management framework for the operator’s well stock. The program provided a clear and auditable view of well integrity status across the asset base, supported by scheduled integrity testing, defined remediation pathways and well-specific Integrity Management Plans. As a result, the operator achieved compliance with statutory obligations and gained improved visibility and control of integrity risks across its wells.
