Citation: IEAGHG, "Wellbore Integrity Network Summary Report", 2012-01, December 2012.

Publication Overview

The purpose of this report is to describe the Wellbore Integrity Network, summarise past meetings, outline key findings and identify current state of knowledge

Publication Summary

The network meetings have presented detailed information from industrial analogues to storage, especially from the oil and gas industry including North American CO₂-EOR and acid gas disposal projects. Statistics on wellbore leakage and failure rates have been presented and discussed, whilst best practice guidelines have been debated. Research over the last 6 years has greatly improved our understanding of processes linked to potential alteration and degradation of wellbore materials, especially cements. Much of the relevant research is included within presentations made at network meetings
