BEST PRACTICE RECOMMENDATIONS FOR RE-USING EXISTING WELLS FOR CO₂ STORAGE

Work Package 5

The aim of WP5 is to develop a series of best practice recommendations for well re-use, intended to provide a frame of reference for operators and regulatory authorities. Partners from all participating countries are involved, and input will be collated covering both technical and non-technical aspects from across the REX-CO₂ work programme. Recommendations need to cover all aspects of well re-use, from characterisation of current well status and condition, workover and remediation requirements for the operational phase, monitoring, and abandonment procedures. A key objective of the REX-CO₂ project is to enable operators to develop effective well re-use plans in compliance with regulatory requirements by provision of these technical best practice recommendations.
